Highlights of Solar and Geomagnetic Activity  
05 - 11 February 2024  
   
Solar activity ranged from moderate levels to very high levels this Click on link below  
period. In total, one X-class flare and 18 M-class flares and were to read the full weekly  
observed. The largest event was an X3.3 flare at 09/1314 UTC from http://services.swpc.noaa.gov/text/weekly.txt
Region 3575 (S36, L=177, class/area=Dkc/270 on 05 Feb), which was  
beyond the SW limb at the time of the event. Region 3576 (S16,  
L=057, class/area=Fkc/740 on 11 Feb) was the largest and most active  
region this week and produced the bulk of the M-class flare  
activity; most notable was an M9.0 flare at 10/2307 UTC which National Oceanic and Atmospheric Administration logo
 
produced an Earth-directed CME expected to arrive late on 12  
Feb/early on 13 Feb. Other notable activity included a filament  
eruption centered near S37W02 at 08/2000 UTC which resulted in an  
Earth-directed CME expected to arrive on 12 Feb.   
   
The greater than 10 MeV proton flux reached S1-S2 (Minor-Moderate)  
levels following the X3.3 flare at 09/1314 UTC. The solar radiation  
storm began at 09/1530 UTC, reached a peak flux of 187 pfu at  
09/2355 UTC, and decreased below event threshold at 11/1805 UTC. The  
Solar activity is expected to be low to moderate throughout the  
period with M-class flares likely and a chance for X-class flares.   
   
No proton events are expected at geosynchronous orbit, barring  
significant flare activity.   
   
             
Progress Solar Cycle no. 25          
Graphic show CV-Int. levels cycle 25 compared to same stage cycles 21-24 per end Jan 2024.
Highlights January 2024          
   
The solar activity in January 2024 have slowly come out of pause with many regions, though  
the solar activity is rising slowly and many regions have been of very modest sizes.  
   
The 6 rot. average was 103,4 CV-units by end January,  
but the 13 rot. average was 111,1 CV-units by last month end.  
Report-end this MPR 510 for January show we may still approach cycle 23, though 18% behind.  
A total of 831 regions this cycle per 14 February 2024 (410 regions North and 421 regions South).   
At the same time solar cycle 24 produced 633 regions .(264 north and 369 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 (though it may happen a bit earlier). Updates will come.  
   
We reckon there have passed 1543 days of the new cycle by this issue on 15 Feb 2024.  
   
There is a continued production of smaller regions but soon expect more active periods!  
The appearance of region 3576 and heavy flare activity show some very active periods to come!  
   
Solar Flux onset occurred 30 September 2022.

Supergroups-catalogue:  
CV-Helios Network is currently working on a catalogue with drawings or photos  
of the, currently 858, sunspot regions that exceeded 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 2024 or 2025!  Stay tuned!
