Minor geomagnetic storm in progress

minor-geomagnetic-storm-in-progress

A minor geomagnetic storm erupted earlier today, Sept. 28th, causing beautiful Wednesday-morning auroras in Canada and some northern-tier US states. These are, essentially, aftershocks of the severe storm on Sept. 26th. More reverberations are possible tonight. (SpaceWeather)

Solar wind
speed: 469.8 km/sec
density: 2.3 protons/cm3

The Radio Sun
10.7 cm flux: 139 sfu

Planetary K-index
Now: Kp= 3 quiet
24-hr max: Kp= 5 storm 

The Solar X-Rays are starting to get active once again. Two flares measuring C9.3 and M1.2 have taken place around Sunspot 1302 which is now in the middle of the visible solar disk. A short 10cm Radio burst (TenFlare) accompanied the first flare. Watch a movie presentation below of the M1.2 Solar Flare. Any large explosions at this point would have planet earth in its path.

Minor geomagnetic storming did flare up again on Wednesday, but things are now returning to more quiet levels. (SolarHam)
