Highlights of Solar and Geomagnetic Activity  
07 - 13 September 2020  
 
Solar activity was very low throughout the reporting period. No  
spotted regions were observed on the visible disk and no  
Earth-directed CMEs were observed in available coronagraph imagery.  
 
No proton events were observed at geosynchronous orbit.  
 
The greater than 2 MeV electron flux at geosynchronous orbit was  
normal to high levels throughout the reporting period. GOES-16 peak  
flux reached 10,200 pfu at 07/1600 UTC.  
 
Geomagnetic field activity was quiet to unsettled under a mostly  
nominal solar wind regime.  
 
Forecast of Solar and Geomagnetic Activity  
14 September - 10 October 2020  
 
Solar activity is expected to be at very low levels for the outlook

News August 2020          
 
A little repetition from last issue of MPR:  
HAS SOLAR CYCLE 24 FINALLY ENDED?  
Yes.  
The lowest solar flux adjusted center averaged 13 rotations indicate 23 Nov 2019 as the approx. min. date.  
The low level did not reach as low as for transition solar cycles 23 and 24, at 67,93 on 01 Nov 2008.  
This time, the cycle transition occurred on 23 Nov 2019 at pfu 69,02, same calculation as above.  
Now, using the same calculation scheme as above on our CV-International numbers,  
we end up as 10 Nov 2019 as the minimum date with cv 0,48.  
Using the other commonly used Relative numbers we end up with the same date as above CV-I,  
i.e. either 09 or 10 Nov 2019 at Ri 1,46.  
Between 12 and 20 Dec 2019 it may seem we made the maximum number of spotless days  
ending up at 255 days with definate days under cv=0,5.

Solar Cycle 25 is Coming to Life  
AUGUST 4, 2020 / DR.TONY PHILLIPS  
August 3, 2020: There is no longer any doubt. New Solar Cycle 25 is coming to life. The latest sign  
came today with the emergence of a new sunspot group, AR2770, inset in this magnetic map  
of the sun’s surface from NASA’s Solar Dynamics Observatory  
 
Kjell Inge Malde  
AUGUST 6, 2020 AT 8:49 AM  
Calculating the 10,7cm solar flux 2800 MHz from Penticton, Canada, giving a 13-rotation centered  
average for the 1AU adjusted values, I have landed on 2019 November 23 as a center minimum date.  
This correspond fairly well with R-I, CV-I, maximum spotless days on the mentioned values,  
and also some of the various measurements done by Nobeyama in Japan.  
All indices should indicate solar cycle 25 has well entered the front door.  
 
APOLOGIES  
Due to my recent moving of private address, the registrations of CV-submissions  
took longer time at the beginning of September.  
The hard work packing, transporting, reerections, furbishing, etc., took a long time,  
but those days are now more or less over, and everything nearing normal.  
Thank you very much for your patience!

Region 2770 taken from SOHO on 05 Aug 2020 at 1500 UTC.  
Postioned at S22 long. 24 in rot. no. 2233,  
yet another region in the solar cycle 25 history,  
and covered a max of 160 day of this image.  
It was classified at CSO on 5 of the days.  
The distinct group decayed before reching the W lomb.  
Regions stable and unremarkable but numbers may be picking up again now.  
 
When the tiny group 2772 disappeared on the 22nd,  
we have, until editorial close, had 25 consecutive days with a blank disk,  
and looking at Stereo-A images not much of interest may turn up.  
 
 
 
 
Please feel free to send in your images for publication here!  
Thank you.
