A moderate G2 geomagnetic storm watch has been issued by the NOAA SWPC for Monday, 22 January and Tuesday, 23 January. This is due to the expected arrival of a coronal mass ejection launched by a eruption south of sunspot region 3557 early yesterday morning.

Happy New Year to all of our visitors and fans! How do we celebrate that? With a major solar flare of course! The Sun was kind enough to produce some spectacular fireworks yesterday just two hours before UTC midnight. It was a major X5.0 (R3-strong) solar flare that peaked at 21:55 UTC. Sunspot region 3536 is the source of the eruption which is just rotating into view on the east limb. This is actually the return of sunspot region 3514 which produced an X2.8 solar flare during the previous solar rotation.

Solar activity has been fairly quiet the past few days as there are currently no noteworthy sunspot regions on the earth-facing solar disk. However, a different kind of interesting solar feature is currently staring right at us on the earth-facing solar disk and that is a trans-equatorial coronal hole.

Yesterday's X2.8 solar flare (which is the strongest solar flare since 2017) came from sunspot region 3514 which is rotating towards the west limb. It became clear quite soon following the event that it would be eruptive but is there a chance that the resulting coronal mass ejection (CME) arrives at Earth? Keep on reading for the answer!

A major X2.87 (R3-strong) solar flare just peaked at 17:02 UTC. Sunspot region 3514 is the source of the eruption.

The geomagnetic storm which was the result of a coronal mass ejection impact from the M9.8 solar flare has now subsided. The north-south (Bz) component of the interplanetary magnetic field is pointing northwards which is preventing any kind of geomagnetic unrest at the moment. We did peak at the strong G3 geomagnetic storm level which caused some very nice auroral displays at lower latitudes than usual. So does that mean we need to wait for weeks and weeks before the next geomagnetic storm? No! A very large coronal hole is currently facing our planet sending a high-speed solar wind stream towards us.

A near X-class (M9.8) solar flare (R2-moderate) erupted yesterday at 19:50 UTC. It was sunspot region 3500 which was pretty much on the center of the earth-facing solar disk at the time that was the source of this eruption.

A full halo Coronal Mass Ejection (CME) left the Sun around 12 UTC on 9 November. The CME was the result of a filament eruption close to the center of the earth-facing solar disk.

Wow! Now that was what you call an almighty storm! Two distinct coronal mass ejection arrivals yesterday sparked a geomagnetic storm that peaked at the strong G3 (Kp7) level. This sparked spectacular and vivid aurora displays which were seen from all over Europe, southern parts of Australia and New Zealand. We admit that we were actually surprised by how far south in Europe people were spotting the aurora. We have seen images from pretty much every European country and even as far south as Turkey! Yes! Turkey! Incredible stuff! This amazing aurora display is yet another example of why you need to remain vigilant during coronal mass ejection arrivals! You never know when that chance comes that you will be able to spot the aurora from your own back yard or balcony!

It feels like it was ages ago that we made a news article where we talked about a good-old reliable coronal hole but today is the day as we actually have a fairly large coronal hole facing our planet today!
