Highlights of Solar and Geomagnetic Activity  
08 - 14 July 2024  
   
Solar activity was at low to strong levels during the period. R1 Click on link below  
(minor) solar radiation storms were observed on 08, 10, 11, 13 and to read the full weekly  
14 Jul, R2 (moderate) storms were observed on 13 Jul and R3 (strong) http://services.swpc.noaa.gov/text/weekly.txt
storms were observed on 14 Jul. Regions 3738 (S09, L=213, class/area  
Fkc/1140 on 14 Jul), 3745 (S15, L=156, class/area Dro/020 on 13 Jul)  
and 3747 (S24, L=155, class/area Cso/180 on 13 Jul) contributed a  
majority of the activity. None of the activity resulted in any  
Earth-directed CMEs.  National Oceanic and Atmospheric Administration logo
 
   
No proton events were observed at geosynchronous orbit.  
   
The greater than 2 MeV electron flux at geosynchronous orbit was at  
normal to moderate levels.   
   
   
   
   
Solar activity is expected to be at low to moderate levels  
throughout the period.   
   
No proton events are expected at geosynchronous orbit.  
   
The greater than 2 MeV electron flux at geosynchronous orbit is  
             
Progress Solar Cycle no. 25          
Graphic show CV-Int. levels cycle 25 compared to same stage cycles 21-24 per 14 Jul 2024.
Highlights June 2024          
   
The solar activity in June 2024 was a very active month with large regions.  
Regions worth mentioning are 3709, 3712, 3713 and 3716.  
On the 20th June region 3712 reached 1140 mvh and then became SuperSunspotregion no. 862 since 1874.  
   
The 6 rot. average for solar cycle 25 now really competes cycle 23 very close,  
and 13 rot. average is not far behind either.  
   
A total of 998 regions this cycle per end July 2024 (489 regions North and 509 regions South).   
At the same time solar cycle 24 produced 752 regions .(332 north and 420 south).  
   
Latest prediction indicate maximum in late July/August 2025.   
Norhtern hemisphere may even have had its maximum already (autumn 2023).  
We see a fairly flat maximum where spring and summer 2025 may have max.-activity. Updates will come.  
   
We reckon there have passed 1694 days of the new cycle by this issue on 15 May 2024.  
   
The appearance of region 3664 and heavy flare activity persisted on its return.  
This region had three orbits before it decayed.  
   
Solar Flux onset 13 rot. ctrd. on 30 Sep 2022, next was offset min. 13 rot. On 24 Apr 2024.  
The offset in April should now indicate the road towards maximum in 2025!  
   
Please remember you are always welcome to contribute with drawings and photos!  
   
Need for new members!  Do you know any amateur solar astronomer that know or like to learn classifications?

Supergroups-catalogue:  
CV-Helios Network is currently working on a catalogue with drawings or photos  
of the, currently 863 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 in 2025!  Stay tuned!
