#Weekly Highlights and Forecasts

Highlights of Solar and Geomagnetic Activity 04 - 10 October 2021

Solar activity was very low over 04-06 Oct. Low levels of solar activity were observed on 07-08 and 10 Oct, and moderate solar activity was observed on 09 Oct. Region 2882 (N17, L=157, class/area=Dho/280 on 09 Oct) produced the majority of the C-class flare activity in addition to the largest event of the period, an

M1/2b flare (with Type-II and IV radio emissions) at 09/0638 UTC. An associated full-halo CME signature was observed in LASCO C2 imagery beginning at 09/0712 UTC, and is likely to arrive at Earth around midday on 11 Oct.

No proton events were observed at geosynchronous orbit.

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

Geomagnetic field activity was quiet on 07-09 Oct, quiet to

News October 2021

Solar activity is still low but number of regions are slowly increasing.

As shown in this issue, the CV as 13-rot. centered averages are now higher than for solar cycle 24 at the same time of progress from minimum!

According to solar flux we are now ahead with about 7 percent compared to cycle 24.

There were a total of 18 sunspot regions developing in September 2021.

List of 7 significant sunspot regions developing in October 2021:

Activity cut from Sunspot Region Summaries from NOAA:

10 Oct: Region 2882 (N17W01, Dho) produced an M1/2b flare.

29 Oct: Solar activity reached high levels. Region 2887 (S27W15, Dhi) produced an X1 flare.

30 Oct: Solar activity reached moderate levels.

Region 2891 (N17E41, Dki) produced an M1 flare observed at 29/0242 UTC. 31 Oct: Region 2887 (S27W54, Cso) produced an M1/1f flare.

Apart from this solar activity varied from very low to low and mostly C-class flares most significant.

Solar Max.: Originally July 2025, which now may occur end Feb/start March 2025.

We wish you all lots of sunny days, happy observing and good luck further on in 2021!
