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!

S2 solar raditation storm, Earth-directed CME

S2 solar raditation storm, Earth-directed CME

Solar protons reached the moderate S2 threshold today for the second time this solar cycle. Moderate S2 solar radiation storms will cause problems with HF radio communications at polar latitudes and have a minor impact on some types of satellite services, This is all due to the highly eruptive M4.1 solar flare from the west limb which peaked at 15:58 UTC yesterday. This solar flare launched an impressive coronal mass ejection but it is not aimed at Earth.

M5.7 solar flare

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.

Strong M-flares, Filament eruption with CME

Strong M-flares, Filament eruption with CME

Welcome to July! A month where both our American and French friends celebrate very important holidays with lots of celebrations and fireworks! Our Sun thought it would be a good idea to join in on the celebrations as we have a new sunspot region (AR3372) announcing its presence near the north-east limb with regular M-class solar fireworks, some of these flare have even exceeded the M5 (R2-moderate) threshold like the M6,8 solar flare that took place today and peaked at 08;55 UTC.

X1.0 solar flare from sunspot region 3354

Sunspot region 3354 departs with a major X1.0 solar flare (R3-strong) yesterday at 23:14 UTC as it approaches the west limb.

X1.1 solar flare

X1.1 solar flare

That was unexpected! Incoming sunspot region 3341 produced an X1.1 solar flare (R3-strong) that peaked yesterday at 17:09 UTC. It has almost been 3 months since the last time we had an X-class solar flare and we have to admit getting an X-flare was unexpected!

M-class activity from sunspot region 3311

M-class activity from sunspot region 3311

There as been a lot of M-class flare activity the past few days coming from sunspot region 3311 including an M6.4 solar flare (R2-moderate) which peaked today at 07:32 UTC and an M8.9 solar flare (strongest from this region thus far) which peaked just a couple of moments ago at 12:35 UTC. This latest solar flare is the third solar flare from this sunspot region which peaked above the M5 threshold.

M4.2 solar flare with earth-directed CME

M4.2 solar flare with earth-directed CME

We have had some stormy space weather these first few days of May! Perhaps not stormy in the sense of geomagnetic storms as we only had a maximum Kp value of 6 on the 6th of May and we hit Kp5 today, yesterday and on the 8th of May. But fair enough, not too bad perhaps reflecting on it but we want to focus on the Sun right now as that is where the real action is taking place. She has been popping of with many M-class solar flares, most of which we can thank sunspot region 3296 for.

M2.1 solar flare and a partial halo CME

M2.1 solar flare and a partial halo CME

As you might have noticed... there has been a lot of M-class activity the past few days. Unfortunately the M3.9 solar flare that took place yesterday did not produce an earth-directed eruption as the halo outline was determined to come from another far side eruption. So we are going to ignore all of these solar flares except for one: the M2.1 flare that peaked at 08:01 UTC today.

Coronal mass ejection impact

Coronal mass ejection impact

The coronal mass ejection from the M1.7 solar flare that took place two days ago has arrived at the DSCOVR satellite. We admit... this coronal mass ejection arrived earlier than we expected!
