Activity level: mostly low X-ray background flux (1.0-8.0 A): in the range B3.5 - B8.5 Radio flux (10.7 cm): a fluctuation in the range 80-130 Events: class C (1-8/day), class M (0-3/period), class X (0/period), proton (0/period) Relative sunspot number (Ri): in the range 99 - 130 Martina Pavelkova RWC Prague, Astronomical Institute, Solar Dept., Ondrejov, Czech Republic
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 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.
