M5.7 solar flare
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.
