Chapter 1—Ruminations and Rehabilitations

Skye woke up in a hospital bed on Peterson Air Force Base near Colorado Springs the afternoon following the shooting, which was Saturday. Her chest and belly ached miserably, and there was a taste in her mouth as if all the armies that had ever marched had tramped across her tongue.

"Uhg," she groaned softly, smacking her mouth in disgust.

As sensation and full consciousness slowly returned, a previously unnoticed grip on her fingers tightened, and a familiar, English voice murmured, "Skye?"

"H-holmes? Is that you?" Skye wondered, confused.

"Yes, Skye. I am here."

Through the slits of her barely open eyelids, she saw a dark form loom over her, coming to sit gingerly on the edge of the bed. As her eyes finally responded to her mental command to focus, the form resolved into Holmes, who was now dressed in the RAF uniform he kept in their office. He reached for something beyond her range of sight, then brought his left hand back with a small plastic cup, a straw tucked inside it.

"Here. Sip this." His right hand never let go her own. Skye allowed him to place the straw in her mouth before sipping the cool water.

"Oh, that's better. My mouth tasted nasty."

"That would be the narcotics," he replied, the hint of a smile on his tired face as he returned the cup to the bedside table.




* * *

"Oh." Skye gave him a bleary-eyed scrutiny, and Holmes read it accurately.

"No, my dear. Watson broke me of that habit some years ago, at my own request, I might add. And I must confess, I find this world of yours stimulating enough that I have no interest in such substances, anyway." He allowed the hint of expression to become a full-fledged smile, and he said, "Dear old Watson, it seems, was equally as determined as dear new Skye. But it does mean I have some experience with nasty tastes in one's mouth."

"How bad?" Skye gestured to her bandaged, aching torso.

"Punctured left lung, lacerated spleen." Holmes drew a deep, pained breath. "Considerable blood loss. The spleen was not so damaged as to require complete removal, fortunately. There is speculation it caught a ricochet; the bits of metal pulled out from that organ definitely did not add up to a complete bullet, as opposed to the one in the lung, which emerged intact. But lung and spleen are repaired now, and you are getting blood." He gestured at the IV bags hanging nearby, where a deep-red fluid dribbled through a tube into her arm. "In fact, one of those is mine. They were low on your blood type." Then he quipped, "And relative to some of the people in this age of yours, it seems I am quite the healthy specimen." He paused, becoming very serious. "Skye, I must apologise…I had to break my oath to you."

A Plea for Help: Colorado Springs and the Waldo Canyon Fire

For the last twenty-four hours my eyes have been glued to reports - television, multiple websites, and friends - about the Waldo Canyon wildfire. This fire has exploded in that time, and is now twice the size it was this time yesterday. It is jumping reservoir lakes and is threatening to jump I-25 in and around Colorado Springs, or as I know it, CoSpr.

I have friends who live there. I have been there many times. I recognize the scenes, the neighborhoods and mountainsides that are burning. They are places I have talked about in my Displaced Detective series, which is based in the CoSpr area. I am terrified for my friends, I am horrified at the destruction, and I am dreading the potential loss of the historic district. When I read the evacuation orders and the boundaries of the evac zones, I recognize the landmarks they are using. This whole thing is a living nightmare. I cannot even imagine the mental state of those who are living it.

There are many homes being burned in this fire. There are numerous reasons for this. One is that, between the USAF Academy, Peterson AFB, Schriever AFB, and Cheyenne Mountain, with their associated civilian contractors, there is a continual flux of people moving into and out of the area. People who have never lived in what is a kind of high desert before do not know how to protect themselves against wildfires. They pick a home site based upon its view, its aesthetics, then build a home like what they are used to, or what they envision is appropriate (e.g. a log cabin style), and landscape as they would in a well-watered area in the East. This is a recipe for disaster.

Aesthetic views notwithstanding, the homes should be as fireproof on the outside as possible. Nearby trees should be removed, so that they cannot catch fire and fall atop the house. Landscaping should be kept well AWAY from the house, and be of plantings that are relatively inflammable (although at temperatures hot enough to melt iron and steel, that can be a moot point). Plants should be surrounded by stones and pebbles, not organic mulch.

But in general this doesn't happen and outside the city limits proper there are no rules about such things. (I'm not sure what rules there are within the city limits either, but you get the idea.) And there are always things that happen: I was informed that only about a week or so ago a tremendous hailstorm came through that did severe damage to the flame-resistant shake roofs, breaking tiles galore, and many have not yet had a chance to repair the damage. Gaping hole in the fire defense.

So this is happening. And people are in harm's way. People are losing their homes and businesses. What can we do?

Go here : https://american.redcross.org/site/Donation2?idb=160451275&df_id=3791&3791.donation=form1

This is the donation site for the Colorado Red Cross. You are welcome to donate whatever you like to whatever you like, but the Red Cross chapter for CoSpr is known as the Pikes Peak chapter, in the pull-down menu. I know that the son of a friend in the area has volunteered for Red Cross service - I think as a medic/EMT, though I could be wrong - despite the possibility that his home may be under evacuation notice at any time. I know people who are likely on the front line of that fire somewhere. Maybe we aren't there, but we can "get their backs." Donate, please, I urge you.

Space Weather - The Carrington Event


In August of 1859, during historic Solar Cycle 10, something very strange began to happen. The Sun, as it neared solar max, grew unusually active. It produced prolific numbers of sunspots and flares, some of which were visible to the naked eye. This continued through the end of the month, until, just before noon on September 1, British astronomer Richard Carrington, just 33 and already acknowledged as one of England's premier solar astronomers, observed an incredibly brilliant solar flare – a flare that was easily visible to the naked eye. In later times, this single flare became known as The Carrington Super-Flare. In his own words from his scientific records:

“...Within the area of the great north group [of sunspots]...two patches of intensely bright and white light broke out...My first impression was that by some chance a ray of light had penetrated a hole in the [projection] screen...for the brilliancy was fully equal to that of direct sun-light; but by at once interrupting the current observation, and causing the image to move by turning the R.A. [right ascension, an astronomical coordinate akin to longitude] handle, I saw I was an unprepared witness to a very different affair...The instant of the first outburst was not 15 seconds different from 11h 18m Greenwich mean time, and 11h 23m was taken for the time of disappearance [from the telescope's view]. In this lapse of 5 minutes, the two patches of light traversed a space of about 35,000 miles...”

British amateur astronomer Richard Hodgeson also observed it; Balfour Steward at the Kew Observatory noted a “crochet” effect on the observatory's magnetometer. (A “crochet” is also sometimes called a Sudden Ionospheric Disturbance, or SID. It is when a solar event produces an abnormally high plasma density – remember, plasma is like the stuff in your fluorescent lights – in one layer of the ionosphere. This in turn creates literal electric currents running through the ionosphere, which magnetometers pick up. It creates something of an invisible lacy pattern in the atmosphere, hence, I suppose, the term “crochet.”)

And all of the previous flares and coronal mass ejections had fairly effectively cleared the interplanetary medium between the Sun and Earth.

The enormous coronal mass ejection produced by the super-flare slammed into Earth in only 17 hours.

The resulting effects lasted several days.

What kind of effects?

Worldwide aurorae for starters. These aurorae were most noted in the Caribbean, where they had never been seen before. Colorado gold miners, awakened by the brightening skies, got up and began cooking their breakfasts, because they thought it was dawn. In Europe and the northeastern United States, newspapers could be read by the light of the aurorae.

Speaking of newspapers, the Baltimore American and Commercial Advisor spoke of the ongoing event in poetic terms. “Those who happened to be out late on Thursday night had an opportunity of witnessing another magnificent display of the auroral lights. The phenomenon was very similar to the display on Sunday night, though at times the light was, if possible, more brilliant, and the prismatic hues more varied and gorgeous. The light appeared to cover the whole firmament, apparently like a luminous cloud, through which the stars of the larger magnitude indistinctly shone. The light was greater than that of the moon at its full, but had an indescribable softness and delicacy that seemed to envelop everything upon which it rested. Between 12 and 1 o'clock, when the display was at its full brilliancy, the quiet streets of the city resting under this strange light, presented a beautiful as well as singular appearance.”

Those dealing in the business of telegraphy did not think so highly of the display. The incredibly intense event, a maximal G5 and S5 by any definition, created induced currents in telegraph wires that were simply impossible to control. Lines and pylons threw sparks, telegraph batteries were blown, telegraphers received severe shocks, and telegraph “flimsy” paper burst into flames.

And yet some telegraph systems continued to function, despite having no batteries to power them. The induced current was simply that strong.

This was the Carrington Event, the most powerful solar/geomagnetic storm ever to occur in recorded history. It was before the advent of electricity, or electronics, or integrated grids and networks, save for telegraph systems, with which it wreaked havoc. Imagine what effect it would have today.


Dibs on the story.    ;-)

Solar-Earth DefCon Levels, Part 2


Now, while all of this stuff is going on in the geomagnetic field, what's happening in space? Hard radiation, and lots of it, that's what. After all, that's basically what's causing the disturbance in the geomagnetic field.

And of course NOAA has another scale that relates to that, called the solar storm scale, and represented by – you guessed it – S.

There's not a direct correlation that I've ever been able to find between the G scale and the S scale, because the S scale is determined by the number of protons of a given energy that passes through, say a square meter in a second. This number is called the proton flux. (In the case of the S scale, the energy of the protons must be greater than or equal to 10MeV, where MeV is mega-electron-volts. An electron volt is very tiny, only 1.6x10-19 joules. So an MeV is an energy of 1.6x10-12 joules. It's not big, but when you're talking about something as small as a proton, it's big enough.)

So at S1, our proton flux is 10 protons per second per steradian per square centimeter. (This is not a very big area. The bigger the number of protons passing through, the bigger the radiation dose.) An S1 is a minor solar storm. According to NOAA, the effects are as follows, “Biological: none. Satellite operations: none. Other systems: minor impacts on HF radio in the polar regions.” This happens a lot, but not quite as often as a G1 – an S1 occurs about 50 times per solar cycle.

An S2 is a moderate solar storm. It requires a proton flux of 100, and occurs half as often as an S1. Effects: “Biological: passengers and crew in high-flying aircraft at high latitudes may be exposed to elevated radiation risk. Satellite operations: infrequent single-event upsets possible. [A single-event upset, or SEU, is when the bit of a computer is accidentally reset to its opposite condition by a proton or electron impact.] Other systems: small effects on HF propagation through the polar regions and navigation at polar cap locations possibly affected.”

S3 is a little stronger still; it's a “strong” solar storm, with a proton flux of 1000. (Note that the solar storm scale is a logarithmic scale like the Richter scale, with each step of the scale having 10x greater proton flux than the previous.) Only 10 of these typically occur per solar cycle, but they aren't pleasant. “Biological: radiation hazard avoidance recommended for astronauts on EVA; passengers and crew in high-flying aircraft at high latitudes may be exposed to radiation risk. Satellite operations: single-event upsets, noise in imaging systems, and slight reduction of efficiency in solar panel are likely. Other systems: degraded HF radio propagation through the polar regions and navigation position errors likely.”

Stepping up to an S4, a severe solar storm, we have a proton flux of 10,000. They are pretty rare, with only about 3 per solar cycle occurring. “Biological: unavoidable radiation hazard to astronauts on EVA; passengers and crew in high-flying aircraft at high latitudes may be exposed to radiation risk. Satellite operations: may experience memory device problems and noise on imaging systems; star-tracker problems may cause orientation problems, and solar panel efficiency can be degraded. Other systems: blackout of HF radio communications through the polar regions and increased navigation errors over several days are likely.”

And finally the granddaddy of solar storms, the S5, the extreme storm. It has a proton flux of 100,000 protons per second per steradian per square centimeter. Simply put, a flood of 100,000 protons is striking every square centimeter (less than half an inch each way), every second. These are very rare, and may or may not occur in any given solar cycle. But they can be devastating. “Biological: unavoidable high radiation hazard to astronauts on EVA (extra-vehicular activity); passengers and crew in high-flying aircraft at high latitudes may be exposed to radiation risk. Satellite operations: satellites may be rendered useless, memory impacts can cause loss of control, may cause serious noise in image data, star-trackers may be unable to locate sources; permanent damage to solar panels possible. Other systems: complete blackout of HF (high frequency) communications possible through the polar regions, and position errors make navigation operations extremely difficult.”

We're fortunate those don't occur very often at all.

But even the typical description of a G5 or S5 doesn't match the strongest geomagnetic storm in history.

Solar-Earth DefCon Levels, Part 1

As I told you last week, NOAA has a scale of geomagnetic activity that ranges from G0 to G5, where G0 is quiescent, and G5 is the worst geomagnetic storm around. Now, we've already talked a little bit about what geomagnetic storms do...

No, we didn't, you say?

Ah, but we did. Back when I told you about all the effects that Coronal Mass Ejections can have. (Solar, Space, and Geomagnetic Weather, Part 4.) Because those sorts of things are what cause the geomagnetic storms.

But probably the best way I can tell you about the effects is simply to quote from NOAA's scale itself (which can be found here: http://www.swpc.noaa.gov/NOAAscales/#GeomagneticStorms).

As I mentioned last week, a G0 is the normal, quiescent geomagnetic field. This holds until the Kp index reaches 5, and then we begin minor geomagnetic storming, with the scale hitting G1. According to NOAA, “Power systems: weak power grid fluctuations can occur. Spacecraft operations: minor impact on satellite operations possible. Other systems: migratory animals are affected at this and higher levels; aurora is commonly visible at high latitudes (northern Michigan and Maine).” These are fairly frequent, with on average close to 2000 per 11-year solar cycle.

At Kp=6, G2 is considered a moderate storm. “Power systems: high-latitude power systems may experience voltage alarms, long-duration storms may cause transformer damage. Spacecraft operations: corrective actions to orientation may be required by ground control; possible changes in drag affect orbit predictions. Other systems: HF radio propagation can fade at higher latitudes, and aurora has been seen as low as New York and Idaho (typically 55° geomagnetic lat.).” These are a little less frequent than G1, but still occur at a rate of about 600 every solar cycle.

When Kp=7, G3 is a strong geomagnetic storm. “Power systems: voltage corrections may be required, false alarms triggered on some protection devices. Spacecraft operations: surface charging [static electricity buildup; this can lead to arcing]may occur on satellite components, drag may increase on low-Earth-orbit satellites, and corrections may be needed for orientation problems. Other systems: intermittent satellite navigation and low-frequency radio navigation problems may occur, HF radio may be intermittent, and aurora has been seen as low as Illinois and Oregon (typically 50° geomagnetic lat.).” These are less frequent still, with on average 200 per solar cycle. Also, as the geomagnetic storms increase in strength, their likelihood of occurrence tends to concentrate around solar maximum, though this is not a hard and fast rule.

At Kp=8, G4 is a severe geomagnetic storm. “Power systems: possible widespread voltage control problems and some protective systems will mistakenly trip out key assets from the grid. Spacecraft operations: may experience surface charging and tracking problems, corrections may be needed for orientation problems. Other systems: induced pipeline currents affect preventive measures, HF radio propagation sporadic, satellite navigation degraded for hours, low-frequency radio navigation disrupted, and aurora has been seen as low as Alabama and northern California (typically 45° geomagnetic lat.). These are rarer still, with only about 100 seen per solar cycle.

And then there's the big boys. Kp=9 means a G5 extreme geomagnetic storm. “Power systems: widespread voltage control problems and protective system problems can occur, some grid systems may experience complete collapse or blackouts. Transformers may experience damage. Spacecraft operations: may experience extensive surface charging, problems with orientation, uplink/downlink and tracking satellites. Other systems: pipeline currents can reach hundreds of amps, HF (high frequency) radio propagation may be impossible in many areas for one to two days, satellite navigation may be degraded for days, low-frequency radio navigation can be out for hours, and aurora has been seen as low as Florida and southern Texas (typically 40° geomagnetic lat.).” These are the rarest of all, but still occur on average 4 per solar cycle.
