#Weekly Highlights and Forecasts

Highlights of Solar and Geomagnetic Activity 04 - 10 January 2021

Solar activity was very low with no spotted groups on the visible disk.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels for the highlight period.

Geomagnetic field activity reached active levels on 05-06 Jan due to recurrent coronal hole high speed stream influences (CH HSS). Quiet to unsettled levels were observed during the remainder of the highlight period.

Forecast of Solar and Geomagnetic Activity

11 January - 06 February 2021

Solar activity is expected to be at very low levels during the

News December 2020

Solar activity is still growing at the start of the new solar cycle 25. Even if December 2020 activity was at far lower levels than November, we still see the chance of developing activity.

In the beginning of the month of December 2020 there were some C-class flares to be observed 3rd to 7th December.

Later in the month more very low activity, C-class flare on the 15th.

Apart from that, only B-class enchancements were observed according to NOAA Space Weather.

Regions:

Region 2786, lat. S17, long. 347, rot. 2238, reached 460 mvh on the 4th December, and classified as HKX, was by far the most active region in November/December 2020. Region 2790, lat. S23, long. 252, rot. 2238, on the 5th December classified as CSO, The small region was mostly classified as an HSX, and was very stable.

Region 2794, lat. S16, long. 345, rot. 2239, reached 220 mvh on 25 December and class HSX, very stable. and class HSX, very stable.

Region 2795, followed 2794, at lat. S18, long. 318, reached 200 mvh on 24 December, and classified as DSO, and as we neared the end of the year, it decayed.
