#Weekly Highlights and Forecasts

Highlights of Solar and Geomagnetic Activity 06 - 12 September 2021

Solar activity was at low levels with C-class activity observed from three separate regions. Region 2864 (N24, L=249, class/area Cso/120 on 07 Sep) produced a C2/Sf event at 08/0009 UTC. Associated with this flare was Type II (723 km/s shock velocity) and Type IV radio signatures, along with a weak, Earth-directed CME. Region 2866 (S18, L=199, class/area Dkc/500 on 09 Sep) produced four C-class events including the largest of the period; a C8/1n at 08/1730 UTC. Region 2868 (S21, L=213, class/area Dhi/300 on 08 Sep) also produced four C-class flares during the period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at high levels on 06-07 Sep with a peak of 3,280 pfu observed at 06/1615 UTC. Normal to moderate levels were observed on 08-12 Sep.

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!

There were a total of 12 sunspot regions developing in July 2021.

Obituary

We have received the sad message that one of our longest and faithully serving members, Germán Morales Chavez, Bolivia, passed away on the 9th September this year.

He became a victim of cancer.

Germán, member number CV-038, has been an active member since 1 Oct 1997 and delivered 7468 CV-observations over that time!

A really good solar observer and solar friend who will be sadly missed

in our network and our goals for another way of doing solar observations. Rest In Peace, dear friend!

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!
