As of Maine Time 7:38 PM: Solar Wind Speed: 496 km/sec Solar Wind Magnetic Fields: Bt 4 nT, Bz -1 nT WELL, just when I told you that I didn’t think there’d be any more activity from this period. Surprise. NOAA didn’t forecast it, either. But, I’m seeing negative solar wind trajectory. It’s not super strong but neither was last night, and plenty […]

An active substorm is in progress. We had a pretty good dip right at 19:46 UTC, which equates to 3:46 PM, so not long ago. (Count backward 4 hours from 19:46 and convert from 24 hour time.) Some chances we may see a few dips down to southerly bZ right at first dark, and through […]

Welcome to the new Universal Day. A substorm is developing right now, but, not a big one. Clouds are clearing out over much of the state. The webcam is showing clearing over Katahdin. Any viewing will happen just at dark, and I don’t know for how long. The GOES sun image isn’t showing a coronal […]

It was really hard to drag myself out of bed, since I was up until midnight, due to a geomagnetic substorm I was trying to pinpoint. NOAA data was lagging, and other data from other sources was also seemingly lagging. All I had was the NOAA three-day, which is a broad swath, the NEOC webcam, […]

NOAA forecasts heightened activity for August 20, but between 15-21 UT, which equates to mid-day times. Not set in stone, storms can come sooner, keep an eye out later for the forecast.

UTC 3:52 Sudden IMF surge visible on Katahdin webcam. Weak but coming and going for a few hours. Southern and Midcoast Maine won’t see much due to clouds/weakness of storm/being in the cheap seats. Northern Maine is in the clear, some wispy clouds over Katahdin. Wind is headed north again right now at 4:28 UTC […]
