The active regions in Lasky’s video are mostly new. They either appeared for the first time or ballooned in size from an existiing spot over the weekend. One of them, sunspot AR3055<\/a>, is truly awesome, stretching more than 100,000 km from end to end with more than a dozen dark cores. It is almost directly facing Earth, and poses a threat for strong flares.<\/p>\n\n\n\n To make the video, Lasky capped his telescope with a solar filter tuned to the glow of ionized calcium (CaK). CaK filters are excellent detectors of “sunspot froth”–the bubbly, turbulent sea of magnetism that surrounds active sunspot groups. Every sunspot in the video is surrounded.<\/p>\n\n\n\n :Product: Geophysical Alert Message wwv.txt Space weather for the past 24 hours has been minor.
