Solar Update - Sunspot 1040 remains a fairly large sunspot group and there remains slight chance for an M-Class flare. The Solar X-Ray Flux background levels are in the B-Class territory and holding steady.
The solar flux reached a daily max of 90.8 on Monday and ended with an average of 89 which is a new record for Cycle 24.
Sunspot 1040 (Monday)
Geophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic field was quiet to unsettled. Solar wind observations from the ACE spacecraft indicated the onset of a co-rotating interaction region around 11/0844Z. Solar wind velocity increased from around 357 km/s to a max of 542 km/s at around 11/1540Z. The interplanetary magnetic field (IMF) activity showed an enhancement of total field of 14 nT, and the southern component of the IMF ranged between +10 nT and -9 nT.
Geophysical Activity Forecast: The geomagnetic field is expected to be quiet, with isolated unsettled levels for the next two days (12-13 January) due to a coronal hole high-speed stream. Quiet levels are expected on day three (14 January).
