Highlights of Solar and Geomagnetic Activity  
06 - 12 November 2023 http://services.swpc.noaa.gov/text/weekly.txt
   
Solar activity ranged from low to moderate levels. Low levels were  
observed on 06-10 Nov and again on 12 Nov. Moderate levels  
(R1/Minor) were observed on 11 Nov due to an isolated M1.2/Sf flare  
at 11/1729 UTC from Region 3477 (S15, L=227, class/area Cko/350 on  
05 Nov). Other activity included an eruption centered near S15W15  
around 09/1115 UTC. An associated CME was first observed in  
SOHO/LASCO C2 imagery at 09/1148 UTC as an asymmetric halo.  
Modelling of the CME had an arrival around 11/2000 UTC. Another CME  
was associated with an eruption near Region 3484 (S15, L=215,  
class/area Cai/080 on 12 Nov) occurring at 10/1900 UTC. The  
associated CME was observed off the WSW limb beginning at 10/2000  
UTC. Modelling of the CME suggested a possible grazing influence  
late on 15 Nov.   
   
   
   
   
   
   
   
   
   
   
             
Progress Solar Cycle no. 25          
The above graphic show CV-Int. levels solar cycle 25 compared to same stage previous cycles 21-24.
Highlights October 2023          
The solar activity in October 2023 has come to a great pause, though  
the solar activity is rising slowly and many regions have been of very modest sizes.  
The 6 rot. average was setback about 3,5 months to 114,8 by end October,  
but the 13 rot. average was only setback about 4 weeks to 110,9 by last month end.  
Report-end this MPR 507 for October show we are now about 18 CV-units below cycle 23!  
A total of 713 regions this cycle per end October 2023 (353 regions North and 360 regions South).  
At the same time solar cycle 24 produced 561 regions .(230 north and 331 south).  
Predictions may indicate an upward trend for December and especially January 2024.  
Situation nowadays with low activity sure would need a good uplift now!

We expect a major upgoing of CV-I totals later on this year.

3468,16.10.23,17.10.23,26.10.23,-10,81,2276,130,HAX,7  
   
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 1426 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 expect more active periods!
