Re: solar flare



I received the following news item this morning:
 
Space Weather News for June 7, 2000

Following close on the heels of yesterday's two X-class solar flares, a
third powerful X-class flare erupted today at approximately 1545 UT.  Soon
afterward, coronagraphs on the orbiting Solar and Heliospheric Observatory
detected a faint full halo coronal mass ejection. It appears to be heading
in the direction of Earth at ~800 km/s.  This latest full halo CME will
probably extend the geomagnetic disturbances expected to begin on Thursday
when an interplanetary shock wave spawned by a CME on June 6 collides with
our planet's magnetosphere.  Aurora watchers are advised to be on the alert
for Northern Lights beginning after sunset on Thursday, June 8.

As for radiation exposure, didn't someone on Radsafe propose a web site that would publish this type of information?  Did he know something the astronomers didn't?

The news says we have a substantial solar flare on the way.  Most represent
minimal radiation (dose) impact at sea level, but several in the past were
observable.
Question: Who looks for this data and where is it likely to be posted?  NASA?
Any indication that the high altitude flyers, e.g., the Concorde, are
taking preventive measures?
