A coronal hole is facing our planet today which is sending a high speed solar wind stream towards us which could cause enhanced geomagnetic conditions (and thus aurora!) in the days ahead.

Solar activity has been on the rise again thanks to flaring activity coming from sunspot region 3947. It has been responsible for multiple M-class events and three low-level X-class events including an X1.8 solar flare today that peaked at 12:48 UTC.

Our Sun remains fairly active today but no coronal mass ejections were launched today with a clear earth-directed component. We do however want to talk about yesterday's events again as more data and opinions have emerged...

It has been quite an eventful day on the Sun with 18 M-class solar flares and even an X1 solar flare. Sunspot region 3936 produced most of these events including the X-flare but also sunspot region 3938, 3939 and 3940 were contributors.

Sunspot region 3932 produced an M9.0 (R2-moderate) solar flare today which peaked at 11:12 UTC. The solar flare was fairly impulsive but it was associated with a Type II radio emission indicating the possible launch of a coronal mass ejection something which we can confirm now thanks to SOHO/LASCO coronagraph imagery.

Good morning everyone it's Sunday and the Sun is up early today with a banger! She unexpectedly produced an X2.2 solar flare which peaked at 09:06 UTC. It is sunspot region 3912 which was the source of this event.

The minor S1 solar radiation storm threshold was reached this evening. This is unfortunately not the result of a front side eruption but a major far side eruption behind the west limb. The Sun's magnetic field or Parker Spiral which wraps around the solar system carries the protons from the far side all the way to the Earth and beyond.

Northern hemisphere sky watchers are having a cracking start to their aurora season. The past few months, we have had major solar flares, coronal mass ejection impacts and in general fairly high geomagnetic activity. Welcome solar maximum! So many people have already spotted aurora from their locations even those who do not live close to the arctic circle. Really amazing to see... and today we have more good news for you as we have a coronal hole facing our planet today which is sending a high speed solar wind stream towards our planet.

Two weekends ago we attended the 2024 Aurora Summit in Wisconsin, USA of which we were a proud platinum sponsor. A truly unforgettable experience to meet so many enthusiastic visitors who use our website and app on a daily basis. An event we will never forget. After that we Europeans traveled the fantastic American south-west so apologies if our updates have been irregular the past 14 days. But for sure, if you have the possibility, be sure to visit next year's summit and maybe we will see you there!
