Eight new sunspot groups emerged over the past week.<\/p>\n
Two appeared on August 30, three more on August 31, another two on
September 2 and one more on September 4.<\/p>\n
Average daily sunspot number declined from 177.1 to 155.3, while
average daily solar flux barely changed from 229 to 230.3.<\/p>\n
Spaceweather.com reported the average daily sunspot number for
August was 200, the highest monthly average in the past two decades.<\/p>\n

Weekly Commentary on the Sun, the Magnetosphere, and the Earth’s
Ionosphere – September 5, 2024 from OK1HH:<\/p>\n
“September 6th was the sixth day of a continuous influx of
solar-origin protons into the Earth’s atmosphere. The likely source
is on the far side of the Sun, probably in AR3792, possibly AR3796.
This influx briefly intensified on 3 September at noon UTC.<\/p>\n
“Overall solar activity remains high. The solar flux is again close
to the values measured on August 6-13, about 27 days ago, or during
the last solar revolution. Summer in the Earth’s northern hemisphere
is slowly coming to an end and shortwave propagation conditions
should improve on average. This is happening, but at a slower and
more erratic pace. The reason for this is the irregular changes in
the activity of the Earth’s magnetic field and the parameters of the
solar wind. Sometimes the changes are even opposite to what we would
expect – for example, on 4 September between 1000 to 1500 UTC there
was a rather significant and unexpected increase in geomagnetic
activity, without any major changes in MUF and overall propagation
conditions.<\/p>\n
“We are now observing only a single small coronal hole on the Sun
now. It is located near the central meridian and there is no active
region nearby. Respectively, all three larger ARs, capable of
producing eruptions of moderate magnitude, are south of the solar
equator. Accordingly, we find no change in the short-term forecasts
from the current state. More optimistic are the medium-term
forecasts, which take into account seasonal changes.”<\/p>\n
