DAY AURORA STORM: Last night, Northern Lights descended into the United
States as far south as Michigan, Minnesota, and Washington, kicking off
an unexpected display of bright auroras for Earth Day. What happened?
A CME that was supposed to miss Earth apparently hit instead,
surprising forecasters. Geomagnetic storms are still underway as April
22nd unfolds; high-latitude sky watchers should remain alert for
midnight auroras on April 22-23. Visit
Spaceweather.com for updates.
WEEKEND
METEOR SHOWER: The auroras tonight may be spiced by an occasional flash
of light. Earth is entering a stream of debris from Comet Thatcher,
source of the annual Lyrid meteor shower. Dark sky observers could see
10 to 20 shooting stars per hour shooting out of the constellation
Lyra. Sky maps and observing tips @
