solar flare alert!

The crew was directed into 'storm shelter' areas on board the station
overnight to seek highest radiation protection, due to a massive new solar
flare.

According to http://spaceweather.com/

Sunspot 930 has just unleashed another big solar flare, an X3-class
explosion at 0240 UT on Dec. 13th...
As a result of the blast, a radiation storm is underway. Based on the
energy and number of solar protons streaming past Earth, NOAA ranks the
storm as category S2: satellites may experience some glitches and reboots,
but astronauts are in no danger.

The explosion probably hurled a coronal mass ejection toward Earth.
(Confirmation from SOHO is still pending.) Sky watchers should be alert for
auroras when it arrives on Dec. 14th or 15th.

Right. But last night's concern wasn't the charged particals
but the speed-of-light nasties.

So, the particles from the CME on the way, is there any concern for the
remaining EVAs on the schedule?

The radiation that they worry about is charged particles, just
much more energetic than the typical particles in the solar
wind or a CME. The energetic charged particles arrive soon
after the x-ray burst, but don't travel at quite the speed
of light.

Good point.

Is this like on the Fantastic Four.

Who is who?

Space is a hostile place.

The problem is that by the time you note the x rays, its all rather too
late. As you say though, you can avoid the slower charged particles. Anyone
find it odd that at this so called low time in the cycle, we should have
this active area? Also, why does it spew its junk our way, or is it in fact
doing it all the time and we only notice when its pointed our way!

To Ya All Do we have observatories around the world constantly
observing the Sun's outer atmosphere? I have opened my universe's
picture scrape book and looking at a coronagraph. It clearly show the
two coronal mass ejections on opposite sides of the Sun I can relate
these charged particles to the lines of force of a bar magnet. most
"loop" back,but some go off in space,and some hit Earth. Do they obey
the inverse square law? Are we lucky that they "loop"? I think so. The
chronograph looks like a metal washer,and with ist hole in the
center,and you can see the granular surface. We have to be amazed by
this giant ball of light and heat. It is 99.9 percent of all there is
of the Solar System Bert
