Solar activity
ranged from moderate to high levels. Region 3697 |
Click on link below |
|
|
(S18, L=350,
class/area=Fkc/350 on 03 Jun) was the most active |
to read the full weekly |
|
sunspot region
this period and produced 14 (R1) Minor events and two |
http://services.swpc.noaa.gov/text/weekly.txt |
R2 (Moderate)
events; the largest of which was a long-duration |
|
|
|
|
M9.7/1f flare
at 08/0149 UTC. Following the M9.7 flare, a SEP event |
|
|
|
|
commenced and
a partial halo, Earth-directed CME was produced. |
|
|
|
|
Region 3697
also produced an M6.1/2b flare at 06/1506 UTC. Regions |
|
|
|
|
3695 (N27,
L=030, class/area=Cao/50 on 03 Jun), 3703 (S08, L=327, |
|
|
|
|
class/area=Dac/200
on 07 Jun), and 3709 (S10, L=218, |
|
|
|
|
class/area=Cai/140
on 09 Jun) each produced a single R1 event. |
|
|
|
|
|
|
|
|
|
|
|
Solar
radiation storm conditions were observed on 08-09 Jun, |
|
|
|
|
following the
long-duration M9.7 flare at 08/0149 UTC from Region |
|
|
|
|
3697. The
greater than 100 MeV proton flux exceeded 1 pfu beginning |
|
|
|
|
at 08/0225
UTC, reached a peak flux of 8 pfu at 08/0625 UTC, and |
|
|
|
|
decreased
below the 1 pfu threshold at 08/1455 UTC. The greater than |
|
|
|
|
10 MeV proton
flux exceeded the S1 (Minor) event threshold beginning |
|
|
|
|
Solar activity
is expected to reach moderate and high levels |
|
|
|
|
throughout the
period. M-class flare activity is likely-to-expected |
|
|
|
|
with a varying
chance for X-class flares. |
|
|
|
|
|
|
|
|
|
|
|
|
No proton
events are expected at geosynchronous orbit, barring |
|
|
|
|
significant
flare activity. |

Highlights May
2024 |
|
|
|
|
|
|
|
|
|
|
|
|
The solar
activity in May 2024 was very active with large regions, multiple solar
flares, |
|
|
and radio
storms. The apperarance of region 3664
was very active and flare-procucer. |
|
|
On the 10th May
it reached 2400 mvh then becoming the 7th Supergroup this cycle. |
|
|
|
|
|
|
|
|
|
The 6 rot.
average for solar cycle 25 now really competes cycle 23 very close, |
|
|
|
and 13 rot.
average is not far behind either. |
|
|
|
|
|
|
|
|
|
|
|
A total of 962
regions this cycle per end June 2024 (476 regions North and 486 regions
South). |
|
|
At the same
time solar cycle 24 produced 725 regions .(316 north and 409 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. |
|
|
|
|
|
|
|
|
|
|
Reports on
massive auroras, even the more rare red auroras have been reported far south
in Europe and US. |
|
The appearance
of region 3664 and heavy flare activity and radio storms are future
promising! |
|
|
|
|
|
|
|
|
|
Solar Flux
onset 13 rot. ctrd. on 30 Sep 2022, next was offset min. 13 rot. On 24 Apr
2024. |
|
|
The offset in
April should now indicate the road towards maximum in 2025! |

CV-Helios
Network is currently working on a catalogue with drawings or photos |
|
|
|
of the,
currently 861 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! |
