Here is this week’s space weather and geophysical report, issued 2020 Jan 13 0408 UTC.
Highlights of Solar and Geomagnetic Activity 06 – 12 January 2020
Solar activity was very low. Region 2755 (S34, L=355, class/area Bxo/020 on 03 Jan) decayed to plage on 07 January and was absent of significant flare activity during the period. New Region 2756 (N22, L=017, class/area Cro/030 on 09 Jan) produced dual B1 flares at 10/1159 UTC and 10/1445 UTC before decaying to plage on 11 January. Both regions, one in the northern hemisphere and one in the southern hemisphere, presented in satellite imagery with reverse polarity magnetic field structure. No Earth-directed CMEs were observed.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached moderate levels on 09-12 Jan due to coronal hole influence. Normal levels were observed on 06-08 Jan.
Geomagnetic field activity reached active levels on 06 and 09 Jan, unsettled levels on 08 and 10 Jan due to influence from negative polarity CH HSS activity. Quiet conditions prevailed throughout the remainder of the reporting period.
Forecast of Solar and Geomagnetic Activity 13 January – 08 February 2020
Solar activity is expected to remain 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 moderate levels on 13-22 Jan and 05-08 Feb due to recurrent CH HSS influence. Normal levels are expected throughout the remainder of the outlook period.
Geomagnetic field activity is expected to reach active levels on 14-15 Jan and 02-04 Feb, with unsettled conditions on 13, 16 Jan and 01, 05 Feb due to recurrent CH HSS activity. Quiet conditions are expected throughout the remainder of the period.
