|
|
|
Solar activity
ranged from low to moderate levels R1/Minor). Low |
|
|
|
|
levels were
observed on 04, 06 and 08-10 Sep. Moderate levels |
|
|
|
|
occurred on 05
and 07 Sep. On 05 Sep, Region 3421 (N15, L=343, |
|
|
|
|
class/area
Eai220 on 07 Sep) produced 3 M-class flares, the largest |
|
|
|
|
an M2.0/2n at
05/0812 UTC. This region also produced 21 C-class |
|
|
|
|
flares. On 07
Sep, Region 3425 (N23, L=246, class/area Dai/140 on 08 |
|
|
|
|
Sep) produced
an M2.1/1b at 07/1909 UTC. Associated with this flare |
|
|
|
|
was a 1,238 sfu
Type II Sweep. Region 3425 also produced 9 C-class |
|
|
|
|
flares. The
largest region on the disk was Region 3423 (N16, L=279, |
|
|
|
|
Ekc/380 on 10
Sep). This region produced 8 C-class flares. During |
|
|
|
|
the period,
numerous CMEs were detected on both the front and back |
|
|
|
|
side. None were
determined to be Earth-directed. |
|
|
|
|
|
|
|
|
|
|
|
|
The greater
than 10 MeV protons at geosynchronous orbit were |
|
|
|
|
slightly
enhanced on 06-07 Sep due to M-class activity on 05 Sep. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Solar activity
is expected to be at low to moderate levels through |
|
|
|
|
the forecast
period. M-class flaring (R1-R2/Minor-Moderate) is |
|
|
|
|
expected to
dominate from 15-28 Sep when old Region 3413 (N10, |
|
|
|
|
L=099) returns
to the visible disk. |
|
|
|
|
|
|
|
|
|
|
|
|
No proton
events are expected at geosynchronous orbit. |

Highlights
August 2023 |
|
|
|
|
|
The solar
activity is still rising though many regions have been of modest sizes. |
|
|
|
However, both
CV-I 6 and 13 rotational averages have reached interesting values. |
|
|
|
The 6-rot.
averages have now superseded cycle 24, and the first time |
|
|
|
|
this happened
was on 01 May this year! |
|
|
|
|
|
Report-end this
MPR 505 for August correspond to 22nd February 2002 (day 1375), |
|
|
and the 13-rot.
Average is not just 1,14 CV-units off. |
|
|
|
|
When it comes to
the 6-rotation averages we have now passed cycle 23 with 6,53 CV units! |
|
|
A total of 679
regions this cycle per end September 2023 (330 regions North and 349 regions
South). |
|
|
At the same
time solar cycle 24 produced 534 regions .(217 north and 317 south) |

We expect a
major upgoing of CV-I totals later on this year. |
|
|
|
|
|
|
|
|
|
|
|
As mentioned in
last issue, we might reach max. CV-levels at near or just over 300. |
|
|
|
It now seems
that prediction mix of 6 and 13 rotation averages may indicate maximum
23.06.2025 (+/- 113d) |
|
as a time of
maximum for the CV-I (but still, may be one rotation later). Updates will
come. |
|
|
|
|
|
|
|
|
|
We reckon there
have passed 1365 days (solar flux 1402 days) of the new cycle by this issue. |
|
|
We may see a
continued production of large regions and major solar flares and CME's too! |
