Some Solar Cycle 24 Firsts
--------------------------------------------------------------------------------

Sunspot group #11035 near N30W13 has grown into the largest (seven times larger than the Earth) and most magnetically complex (beta-gamma) sunspot group of solar cycle 24. At 0102 UTC the sunspot group released a small C5.3 solar flare, the largest solar flare of solar cycle 24. More small C class solar flares are possible, with a chance for an isolated medium size M class solar flare.
#11035 also produced the first partially geoeffective (Earth facing) coronal mass ejection (CME) of solar cycle 24. The CME will arrive at Earth in a approximately two days and could spark a geomagnetic storm and visible aurora. Another geoeffective CME is possible, with an associated sudden ionosphere disturbance (SID) and shortwave fadeout (SWF).
The sunspot count is 38 which is the highest of solar cycle 24. The solar flux index is 82 which is tied for the highest SFI of solar Cycle 24.
With the increased sunspot count we should see improved propagation conditions on 15 and 12 meters.
