#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

Progress of Solar Cycle 25 on overlay past solar cycles from Day 0 onwards.

News September 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 almost 5 percent compared to cycle 24.

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

On the 8th September we had the highest CV-number for 4 years excactly ( Sep 2017) with 105,4.

Solar cycle 25 update, and comparison solar cycle 24

It seems the P-Index (fall-rise calculations on 13 solar rotations) on solar flux activity hit it with the first curve culmination beginning of September, which mean that next solar maximum may hit in about 6 months earlier than predicted.

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!

Please remember you are always welcome to contribute with drawings and photos!
