|
|
3664 (S17,
L=347, Fkc/BGD on 10 May). This region was resonsible for |
to read the full weekly |
|
41 M-class and
9 X-class flares accounting for approximately 72% of |
http://services.swpc.noaa.gov/text/weekly.txt |
the 74
energetic events observed during the week. It was also |
|
|
|
|
responsible for
several CMEs, On Monday, 6 May the region had grown |
|
|
|
|
to an Ekc/BGD
group, having been a numbered region since 01 May. By |
|
|
|
|
the 8th, it had
more than doubled in size to 1200 |
|
|
|
|
microhemispheres.and
had produced its first three X-class flares. By |
|
|
|
|
10 May, it had
doubled again in size to 2400 microhemispheres and |
|
|
|
|
produced a
total of 6 X-class flares. |
|
|
|
|
|
|
|

Flares and CMEs
noted included the following from Region 3664, with |

Highlights
April 2024 |
|
|
|
|
|
|
|
|
|
|
|
|
The solar
activity in April 2024 was a nice upswing in solar activity. |
|
|
|
|
Though many
smaller regions, the flare activity has been fairly high. |
|
|
|
|
On the 16th
April we saw the 10.000th region (3644) since 1981 August 15, CV-day no. 1. |
|
|
|
|
|
|
|
|
|
The 6 rot.
average for solar cycle 25 approaches cycle 23 more and more, |
|
|
|
and 13 rot.
average is not far behind either. |
|
|
|
|
|
|
|
|
|
|
|
A total of 927
regions this cycle per end May 2024 (462 regions North and 465 regions
South). |
|
|
At the same
time solar cycle 24 produced 699 regions .(302 north and 397 south). |
|
|
|
|
|
|
|
|
|
|
Latest
prediction indicate maximum in August 2025. Norhtern hemisphere may even have
had its maximum already. |
|
We see a fairly
flat maximum where spring and summer 2025 may have max.-activity. Updates
will come. |
|
|
|
|
|
|
|
|
We reckon there
have passed 1633 days of the new cycle by this issue on 15 May 2024. |
|
|
|
|
|
|
|
|
|
|
There is a
continuous massive production of smaller regions and May shoed another
supergroup! |
|
|
The appearance
of region 3664 and heavy flare activity and radio storms are promising! |

CV-Helios
Network is currently working on a catalogue with drawings or photos |
|
|
|
of the,
currently 860 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! |
