Highlights
September 2024 |
|
|
|
|
|
|
|
|
|
|
|
|
The solar
activity in September2024 was a month with lower numbers than August. |
|
|
|
Largest regions
were numbers 3826, 3827, 3812, 3820 and 3828. |
|
|
|
|
|
|
|
|
|
|
|
A new
SuperSunspotregion 3842 (no. 865) appeared on 05 October 2024. |
|
|
|
A close-up from
SOHO HMI on 05 September is featured here. |
|
|
|
|
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 13 rot.
average for solar cycle 25 now supersedes cycles 23 and 24, |
|
|
|
|
while 6 rot.
average already supersedes cycles 22, 23 and 24. |
|
|
|
|
A total of
1102 regions this cycle per end October 2024 (532 regions North and 570
regions South). |
|
|
At the same
time solar cycle 24 produced 826 regions .(375 north and 451 south). |
|
|
|
Latest
prediction indicate maximum is beginning of August 2025. |
|
|
|
|
Northern
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 1786 days of the new cycle by this issue by 15 September
2024. |
|
|
|
|
|
|
|
|
|
Investigating
the Solar Flux 10,7 cm/2800 MHz: |
|
|
|
|
It seems the
last 44 days of 13 rot. averages solar flux in fact is better comparable |
|
|
|
than the equal
rising flux period in February to April 1992! |
|
|
|
|
Number of days
13-rot. averages equal to or over 200 is so far on 44 days. |
|
|
|
Last time this
occurred was in the year 1991 (232 days).. |
|
|
|
|
|
|
|
|
|
|
|
Many reports of
aurora borealis have appeared, even observed from lower latitudes on Earth!
Witnessed! |
|
|
|
|
|
|
|
|
It seems that
Maximum for the Northern hemisphere occurred 05 November 2023! |
|
|
|
(Southern
hemisphere Maximum expected 10 September 2025). |

currently 863 sunspot regions that exceeded 1000 mvh |

in the period
of RGO-USAF tables, that is, from 1874 to the current year. |
