Two M-class solar flares erupted from Region 2182 early Thursday, October 9, 2014. The first event started at 01:30, peaked at 01:41 UTC as M1.3 solar flare and ended at 01:47.
The second M-class erupted immediately after the M1.3.
It started at 01:54, peaked at 01:58 as M1.4 and ended at 02:02 UTC.
Region 2182 has 'beta' magnetic configuration and is located in the southwest quadrant. More information about those two events will be available after the analysis is complete.
NOAA SWPC forecasters estimate 5% chance for M-class and 1% chance for X-class solar flares in the next three days.
A third M-class solar flare erupted from the same region about 5 hours after the M1.4. That event started at 06:48, peaked at 06:59 as M1.2 solar flare and ended at 07:06 UTC.
There are currently 5 numbered sunspot regions on the disk. Region 2186 (S19E60, Cso/beta) exhibited growth as it rotated onto the visible disk yesterday. All other regions were either stable or in decay. None of them currently poses a threat for strong eruptions.

The geomagnetic field was quiet yesterday with an isolated unsettled period from 09:00 – 12:00 UTC due to extended southward Bz.
It is expected to be quiet to unsettled early on October 9 with a chance for isolated active periods (below G1-Minor) overnight due to enhanced magnetic field and possible nighttime sub-storming.
Predominantly quiet conditions are expected on October 10. Quiet to unsettled conditions are expected on October 11 due to effects from a favorably positioned coronal hole high speed stream.
