Geomagnetic activity forecast for the period October 29 - November 03, 2022

Quiet: Nov 2 - 3
Unsettled: Oct 28, Nov 1 - 2
Active: Oct 29 - Nov 1
Minor storm: Oct 29 - 30
Major storm: 0
Severe storm: 0

About Saturday, October 29, and Sunday, October 30, we expect active 
conditions with possible minor storming effect.
A day ago, Friday, October 28, we expect at most unsettled conditions.
After the active/minor storm episode, we expect at most unsettled 
conditions (with possible isolated active event) till the end of 
October.
First three days of November, we expect geomagnetic activity decrease to 
quiet to unsettled level. About November 1 and 2, it has been expected 
likely to unsettled level, quiet to unsettled conditions closer to quiet 
level are expectable the last day of currently forecasted period, 
November 3.

Weekly Commentary on the Sun, the Magnetosphere, and the Earth's Ionosphere October 29 - November 03, 2022

Weekly Commentary on the Sun, the Magnetosphere, and the Earth's Ionosphere
– October 27, 2022
(Free continuation of predictions of the Earth's magnetic field activity,
published in the years 1978 - 2021.)

Not much has been happening on the Sun over the past few days from the
point of view of a terrestrial observer - overall activity has been low. Of
note, the co-rotating interaction region (CIR) hit Earth's magnetic field
on Oct. 22nd, sparking a G1-class geomagnetic storm and bright auroras
around the Arctic Circle.

In the ensuing development, Earth's magnetic field calmed down and active
sunspot regions began to sink beyond the southwestern edge of the solar
disk and others emerged in the northeast.  Although helioseismic maps have
revealed interesting activity on the sun's far side, this it is likely to
end before it emerges on the eastern edge of the solar disk.
