Highlights of Solar and Geomagnetic Activity  
05 - 11 August 2024  
   
Solar activity was ranged from moderate to high levels. 34 events, Click on link below  
which ranged from R1-R3 (Minor-Strong), were observed during the to read the full weekly  
week. Region 3767 (S10, L=318, class/area=Dso/beta on 27 Jul) http://services.swpc.noaa.gov/text/weekly.txt
produced the strongest flare of the period, an X1.7/Sf at 05/1340  
UTC. Two other regions produced X-class activity with an X1.1/2b at  
05/1527 UTC from Region 3780 (S12, L=173, class/area=Fkc/1280 on 09  
Aug) and an X1.3/2b flare at 08/1935 UTC from Region 3777 (S09,  
L=209, class/area=Ekc/460 on 09 Aug).  National Oceanic and Atmospheric Administration logo
 
   
CME activity observed over 07-08 Aug from multiple sources were  
analyzed and considered likely to be Earth-directed with a transit  
time of 3-4 days. An additional CME associated with an M5  
(R2-Moderate) flare at 10/0237 UTC produced a faint halo signature  
first observed in SOHO/LASCO C2 imagery at 10/0312 UTC. Analysis and  
modeling suggested arrival on 12 Aug.   
   
   
Solar activity is expected to reach moderate (R2-Moderate)  
conditions, with a chance for R3-Strong events, over 12-18 Aug due  
to multiple complex regions on the visible disk. R1 (Minor)  
conditions remain likely on most days through the end of the outlook  
period due to the anticipated return of multiple complex regions  
from the Sun's farside.   
             
Progress Solar Cycle no. 25          
Graphic show CV-Int. levels cycle 25 compared to same stage cycles 21-24 per 14Aug 2024.
Highlights July 2024          
   
The solar activity in July 2024 was a highly active month with large regions.  
Regions worth mentioning are 3733, 3738, 3751, 3761, 3762, 3765 and 3770.  
On the 14th July region 3738 reached 1140 mvh and then became SuperSunspotregion no. 863 since 1874.  
In August another one came!  On the 9th August region 3780 reached 1280 mvh and became SSG-number 864.
The total list of SSG can be found at https://www.cv-helios.net/specialreports/regionlisting-SSG.txt  
Daily updates of regions: Hit https://www.cv-helios.net/cvmisc3.html for daily updates!  
The 6 rot. average for solar cycle 25 now supersedes cycle 23 by numbers,  
and 13 rot. average is not far behind either.  
A total of 1034 regions this cycle per end August 2024 (505 regions North and 529 regions South).   
At the same time solar cycle 24 produced 774 regions .(344 north and 430 south)  
Latest prediction indicate maximum is beginning of August 2025.   
Norhtern hemisphere may even have had its maximum in November 2023!.  
We see a fairly flat maximum where spring and summer 2025 may have max.-activity. Updates will come.  
   
We reckon there have passed 1725 days of the new cycle by this issue by 15 August 2024.  
   
MVH: Total 3260 mvh on 09.08.2024  highest since 03.11.2003: 20,8 years ago.   
Regions, number of regions on 18.07.2024: 18, highest number since 09.05.2002: 22,2 years ago.  
 One member, CV-204 Stefan Meister, reported 21 regions on the 18th July!   
CV-Int. 31.07.2024 highest since 28.09.2001: 22,8 years ago.   
CV-USAF 19.04.2024 highest since 23.08.1991: 32,7 years ago   
 and the fourth highest CV-USAF in CV-HN history!   
FLUX adj. solar flux: 30.07.2024  highest since 08.04.1947: 77,3 years ago,   
 3rd highest on record since start Flux measurements on 14.02.1947.  
   
It seems that Maximum for the Northern hemisphere occurred 05 November 2023!  
(Southern hemisphere Maximum expected 10 September 2025).

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!
