The solar flare is directed towards the Earth and does not come alone

Update as of October 11, 2021. “Medium Warning of a Geomagnetic Storm on October 11, 2021” come to earth

Radiation from the glow ionized the upper part of the Earth’s atmosphere. This, in turn, caused a shortwave radio dimming over the Indian Ocean – a blackout map. Pilots, radio amateurs, and ships at sea may have noticed strange propagation effects at frequencies below 25 MHz.

Noticeable. WLA coronal mass ejection (or CME) is a giant cloud of solar plasma moistened by magnetic field lines that are often ejected from the Sun during strong, long-lasting solar flares and filamentous flares.

New images from SOHO confirm that the explosion threw the CME almost directly toward Earth. This is called the “CME corona” because it appears to completely surround the Sun:

Solar storm likely to hit Earth late October 11-12, 2021, which can cause G1 to G2 geomagnetic storms.

A better estimate of CME arrival time may arise from NOAA Computer Modelingwhich is happening now. Stay tuned for updates.

prediction

G2 (moderate) geomagnetic storm conditions are possible on October 11 due to the expected arrival of the CME from October 9.

A G1 (minor) geomagnetic storm is likely on October 11-12. Area 2882 (N17, L = 157) produced a M1/2b flare (with Type II and IV radio emissions) on 06/0938 UTC, and a full halo associated with a full halo was observed in LASCO C2 images as of 07/0912 UTC Global.

Analysis of events and model departures indicate the arrival of CME around noon on October 11, with continuing effects continuing through October 12.
