Surprise! Earth Day Aurora Storm
Source - Space Weather News for April 22, 2017: http://spaceweather.com
EARTH 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 @ Spaceweather.com.
