Geomagnetic activity forecast for the period July 01 - July 07, 2022

Quiet: Jun 30, Jul 1 -7
Unsettled: Jul 3 - 4, 7
Active: 0
Minor storm: 0
Major storm: 0
Severe storm: 0

Geomagnetic activity summary:
After the last active events (June 24 - 26) which did not exceed the 
active level without storming event (local K-index = 4), we expect 
geomagnetic activity decrease to quiet to unsettled level during the 
coming seven days.
More unsettled character of geomagnetic activity can be expected about 
July 3 - 4, and also at the end of currently forecasted period, i.e. 
July 7. Other days, we expect geomagnetic activity at quiet to unsettled 
level, nearer to the lower one.

Weekly Commentary on the Sun, the Magnetosphere, and the Earth's Ionosphere July 01 - July 07, 2022

Weekly Commentary on the Sun, the Magnetosphere, and the Earth's
Ionosphere - June 30, 2022
(Free continuation of predictions of the Earth's magnetic field activity,
published in the years 1978 - 2021.)


 Solar activity has declined over the last seven days. Geomagnetic activity
was highest on June 26 (G1-class geomagnetic storm broke out around
midnight UT on June 25-26) and is lowest since on June 28-29.
 June 26th, a big, bright CME billowed away from the sun's southern
hemisphere.  A slow-moving CME that left the sun could pass close to Earth
on June 30. The near miss, if it occurs, could disturb our planet's
magnetic field.
 Dark filament of magnetism erupted in the sun's northern hemisphere on
June 28th, but no CME was observed after the explosion.
 Shortwave propagation conditions were relatively worst on June 26-27.
After that, they started to improve, but only very slowly due to the
declining solar activity.
