=================================== Weekly Space Weather Highlights =================================== Highlights of Solar and Geomagnetic Activity 06 - 12 November 2017 Solar activity was very low throughout the period under a spotless disk. The only activity was an eruptive filament observed in the NE quadrant beginning at 10/0630 UTC in SDO/AIA 304 imagery. An associated CME was observed off the eastern limb in SOHO/LASCO C2 imagery beginning at 10/0824 UTC, however subsequent analysis showed no Earth-directed component. No Earth-directed CMEs were observed. No proton events were observed at geosynchronous orbit. The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels on 06-07 Nov and reached high levels on 08-12 Nov. The largest flux of the period was 25,349 pfu observed at 11/1435 UTC. Geomagnetic field activity was at quiet to G2 (Moderate) storm levels over the period. The period began with solar wind speeds between 285-355 km/s and total field around 4 nT. At approximately 07/0300 UTC, phi angle switched from a negative solar sector to positive. Additionally, an increase in solar wind speed and total field was observed due to the arrival of a co-rotating interaction region preceding a positive polarity, polar connected, coronal hole high speed stream (CH HSS). Total field reached a maximum of 23 nT at 07/1545 UTC while the Bz component reached a maximum southward deflection of -15 nT at 07/1508 UTC. Solar wind speed reached double peaks of 699 km/s at 08/0004 UTC and 719 km/s at 10/1257 UTC before slowly receding to end of period values near 430 km/s. The geomagnetic field responded with quiet levels on 06 Nov, reached G1-G2 (Minor-Moderate) levels on 07-08 Nov, reached unsettled to active levels on 09-10 Nov, and calmed to mostly quiet conditions on 11-12 Nov. Forecast of Solar and Geomagnetic Activity 13 November - 09 December 2017 Solar activity is expected to be at very low levels. No proton events are expected at geosynchronous orbit. The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 13-14 Nov, 16-24 Nov, and 05-09 Dec due to recurrent CH HSS influence. Geomagnetic field activity is expected to be at unsettled to active levels on 14-23 Nov, 29-30 Nov, and 04-08 Dec with G1 (Minor) levels likely on 20-22 Nov, 04-07 Dec and G2 (Moderate) levels likely on 04-05 Dec due to recurrent CH HSS effects.
