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. For more information, please visit http://www.spaceweather.com 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?
Just an analog guy in a digital
world.

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?
