Watch This Space
Reminder: keep an eye on SpaceWeather.com, as the sun is going crazy with activity at the moment. There are two—count 'em, two— sunspots the size of Jupiter, and they're tossing off powerful solar flares and coronal mass ejections. When one of these heads our way it's Aurora City, and even those of us at 40°N have a chance.
Update: A very large coronal mass ejection took off around 6 AM ET on Tuesday and reached Earth at 1:20 ET Wednesday morning, causing "northern" lights in Texas, California, and Oklahoma (in New Jersey we got rain). There could be more to come!
