Coronal hole faces Earth

Coronal hole faces Earth

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.

Earth-directed CME, M6 solar flare

Earth-directed CME, M6 solar flare

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!

Major X2.8 solar flare

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

Coronal hole faces Earth

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.

M9.8 solar flare with earth-directed CME

M9.8 solar flare with earth-directed CME

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.

Coronal mass ejection impact expected on 11 November

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.

Strong geomagnetic storm sparks aurora all over Europe

Strong geomagnetic storm sparks aurora all over Europe

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!

Coronal hole faces Earth

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!

New forecast predicts quicker, stronger peak of solar activity

New forecast predicts quicker, stronger peak of solar activity

Solar activity has been really low the past few months, much lower than one would expect this close to solar maximum. Strange as Solar Cycle 25 started of with a very decent amount of solar activity signaling that Solar Cycle 25 would likely surpass Solar Cycle 24 in terms of strength. So where are we right now? Did we pass solar maximum? Is this a temporary lull? Is Solar Cycle 25 maybe not going to be as strong as Solar Cycle 24? A new experimental model from the NOAA’s Space Weather Prediction Center (SWPC) might provide an answer...

Stormy space weather ahead

Stormy space weather ahead

A long duration M1.2 solar flare took place around departing sunspot region 3413 yesterday which peaked around 03:52 UTC. This event launched a coronal mass ejection into space which could arrive at Earth in two days time. This would be the second coronal mass ejection that is expected to arrive at our planet in the coming days. After a very quiet August a promising start to September as darkness returns to the northern hemisphere!
