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 |

from Region 3780 (S12, L=173, class/area=Fkc/1280 on 09 |

CME activity

days. An additional CME associated with an M5 |

(R2-Moderate)
flare at 10/0237 UTC produced a faint halo signature |

conditions,
with a chance for R3-Strong events, over 12-18 Aug due |

|
|
conditions
remain likely on most days through the end of the outlook |

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

|
|
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. |

One member, CV-204 Stefan Meister, reported
21 regions on the 18th July! |

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). |

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!
