S2 solar raditation storm, Earth-directed CME
Saturday, 29 July 2023 12:45 UTC
Solar protons reached the moderate S2 threshold today for the second time this solar cycle. Moderate S2 solar radiation storms will cause problems with HF radio communications at polar latitudes and have a minor impact on some types of satellite services, This is all due to the highly eruptive M4.1 solar flare from the west limb which peaked at 15:58 UTC yesterday. This solar flare launched an impressive coronal mass ejection but it is not aimed at Earth.
But that is not all. We actually see another coronal mass ejection on coronagraph imagery from SOHO yesterday and today and that looks like a beautiful asymmetrical full halo coronal mass ejection! Where did that come from you ask? Wonder no more... we had a filament eruption on the earth-facing solar disk yesterday just before midnight and this is indeed the source of this coronal mass ejection. The asymmetrical full halo outline makes it very likely to impact Earth early on Tuesday, 1 August. Active geomagnetic storm conditions are likely with a chance of minor G1 geomagnetic storm conditions after the cloud arrives.

However, we did had a filament eruption yesterday before midnight UTC which launched this asymmetrical full halo CME towards our planet. It is expected to arrive early on 1 August. pic.twitter.com/clrPdot39X
