Last major update issued on October 12, 2015 at 04:05 UT.
The geomagnetic field was quiet to active on October 11. Solar wind speed at SOHO ranged between 435 and 481 km/s.
Solar flux at 20h UTC on 2.8 GHz was 84.6 (decreasing 11.8 over the last solar rotation). The 90 day 10.7 flux at 1 AU was 102.4. The Potsdam WDC planetary A index was 12 (STAR Ap - based on the mean of three hour interval ap indices: 11.5). Three hour interval K indices: 43112233 (planetary), 32233222 (Boulder).
At the time of counting spots (see image time), spots were observed in 7 active regions using 2K resolution (SN: 107) and 6 active regions using 1K resolution (SN: 77) SDO images on the visible solar disk.
Region 12430 [S18E22] decayed slowly and quietly.
Region 12431 [S18E61] was quiet and stable.
New region 12432 [S22E43] rotated into view on October 9 and was numbeered by SWPC 2 days later as new flux emerged. The region has weak polarity intermixing.
S4805 [N18W33] was quiet and stable.
New region S4813 [N18W41] emerged with many small spots.
New region S4814 [N07W56] emerged with a tiny spot.
New region S4815 [S00E08] emerged with tiny spots.
An active region behind the southeast limb could soon rotate into view, this region may be capable of M class flaring.
October 9-11: No obviously Earth directed CMEs were observed in available LASCO imagery.
An extensive recurrent trans equatorial coronal hole (CH695) will be in a potentially geoeffective position on October 8-13.
The geomagnetic field is expected to be quiet to active on October 12-16 due to effects from CH695.
