as a time of maximum for the CV-I (but still, may be one rotation later). Updates will come. Please remember you are always welcome to contribute with drawings and photos!

Highlights of Solar and Geomagnetic Activity  
04 - 10 December 2023 http://services.swpc.noaa.gov/text/weekly.txt
   
Solar activity ranged from low to high levels this period with  
Regions 3511 (S22, L=216, class/area=Fsi/180 on 09 Dec) and 3513  
(N19, L=220, class/area=Eai/220 on 10 Dec) being the primary sources  
of flare activity. The largest event observed was an M5.4/1b flare  
(R2/Moderate) at 08/2307 UTC from Region 3511. In addition to the  
M5.5 event, Region 3511 produced four R1 (Minor) events over 08-10  
Dec. Region 3513 produced five R1 (Minor) events over 05-06 Dec.  
Despite the flare activity and a number of filament eruptions  
observed throughout the week, no Earth-directed CMEs were detected.   
   
No proton events were observed at geosynchronous orbit.  
   
The greater than 2 MeV electron flux at geosynchronous orbit reached  
high levels 08-09 Dec, with normal to moderate levels observed on  
04-07 and 10 Dec.

Highlights November 2023          
   
The solar activity in November 2023 has perhaps slowly come out of pause, though  
the solar activity is rising slowly and many regions have been of very modest sizes.  
   
The 6 rot. average was set 28 CV-units by end November,  
but the 13 rot. average was set about 16,5 CV-units by last month end.  
Report-end this MPR 508 for November show we may still manage to approach cycle 23.  
A total of 766 regions this cycle per end November 2023 (381 regions North and 385 regions South).   
At the same time solar cycle 24 produced 595 regions .(245 north and 350 south).  
   
It now seems that prediction mix of 6 and 13 rotation averages may indicate maximum 14.08.2025 (+/- 2 rot.)  
as a time of maximum for the CV-I (but still, may be one rotation later). Updates will come.  
   
We reckon there have passed 1456 days of the new cycle by this issue.  
   
We may see a continued production of smaller regions for a while   
but by the end of year and January we expect more active periods!

Supergroups-catalogue:  
CV-Helios Network is currently working on a catalogue with drawings or photos  
of the, currently 858, sunspot regions that exceeeded 1000 mvh  
in the period of RGO-USAF tables, that is, from 1874 to the current year.  
Drawings or photos will be collected from the archives of wellknown different observatories!  
Hopefully this catalogue will be published sometime next year!  Stay tuned!
