M5.7 solar flare
Tuesday, 18 July 2023 08:44 UTC
We are in a period with some higher space weather activity as two coronal mass ejections arrived at Earth during the past few days causing multiple periods with minor G1 geomagnetic storm conditions. Despite the short nights, weak aurora was spotted as far south as the Netherlands! Today's highlight is however the strong M5.7 solar flare from sunspot region 3363 which peaked at 00:06 UTC.
The M5.7 solar flare (R2-moderate) was highly eruptive and caused the first moderate S2 solar radiation storm of Solar Cycle 25 which will cause problems with HF radio communications at arctic latitudes and might impact satellite operations as well. The resulting coronal mass ejection is impressive as you can see on the animation below provided by SOHO but we think the probability of it arriving at Earth is low due to the partial halo outline and location of the eruption.
