Interesting. After reading that Spaceweather article, I had my radiation
detector app running on my tablet two days ago, and there was no doubt that
it was picking up significantly more counts per minute than I've ever seen!
However, the background count last night had dropped to almost normal,
indicating that the cosmic ray level had fallen off.

You can get this free "Geiger counter" app on the Google Play store. It is
very good. It uses one of the cameras as a sensor. Written by a German
scientist, it'll also detect radon gas, radium watch dials, the Americium
from a smoke detector,
some rocks, etc.

73, Mike
