Busy Sun! M-class flares and coronal mass ejections!

Our Sun has been really busy the past few days. M-class solar flares are a regular occurrence which shouldn't go by unnoticed if you follow us on Twitter or have our iOS/Android app installed on your mobile devices. To put things in perspective, the 10.7cm Solar Radio Flux is at 228 today which is comparable to what we saw during the peak of the previous Solar Cycle. This Solar Cycle is expect to reach its peak in 2 years time. Does that mean this Solar Cycle will be strong than Solar Cycle 24? Hard to say, but considering the predictions and where we are right now, it is very much possible.

X1.9 solar flare

maandag 9 januari 2023 19:34 UTC

X1.9 solar flare

A lot of sunspots on our Sun today which is a promising start for what should be an exciting 2023 when it comes to solar activity. Sunspot region 3181 and 3182 both have complex magnetic layouts with magnetic delta sunspots and both regions have the potential to produce M-class events. It is however sunspot region 3184 near the limb that steals the show today with the second strongest solar flare of Solar Cycle 25 thus far.

X1.2 solar flare

X1.2 solar flare

A surprise this night from sunspot region 3182 which has just rotated into view. It produced a major X1.2 solar flare (R3-strong) at 00:58 UTC.

Flares, flares, flares!

Flares, flares, flares!

What a crazy couple of days! After what feels like months of relative silence on our Sun she has really been kicking of the past 72 hours. We had 32 solar flares that reached the M-class threshold over this period. Yes, you did read that right. As of writing this article we counted 32 solar flares that peaked at or above the M1 threshold. Did any of these solar flares produce any significant coronal mass ejections?

M5.2 solar flare, Active geomagnetic conditions

M5.2 solar flare, Active geomagnetic conditions

Quite the surprise today! Sunspot region 3141 unexpectedly produced an M5.2 solar flare (R2-moderate radio blackout) that peaked at 00:11 UTC. The solar flare was however impulsive which means it was very short in duration. The resulting coronal mass ejection is very minor and not aimed at Earth.

Active geomagnetic conditions, Coronal hole faces Earth

Active geomagnetic conditions, Coronal hole faces Earth

We are currently seeing enhanced auroral conditions here on Earth. Hard to say what is causing it but the north-south direction of the interplanetary magnetic field has turned southwards which fuels auroral activity. Active conditions (Kp4) have been observed already and minor G1 geomagnetic storm conditions are not impossible. High latitude sky watchers should be alert of possible aurora in the hours ahead.

X1.0 solar flare

maandag 3 oktober 2022 17:26 UTC

X1.0 solar flare

Flares, flares and even more flares! That's the topic of the day! Sunspot regions 3110 and 3112 continue to produce numerous C and M-class solar flares together but an X1.0 solar flare that peaked at 20:25 UTC yesterday from sunspot region 3110 is for sure the highlight of the past 24 hours.

Two strong M-class solar flares

Two strong M-class solar flares

We are not seeing much yet of the anticipated geomagnetic storming conditions but our Sun is really doing its best to distract us from that fact. Solar activity is elevated with two sunspot regions stepping into the spotlight. Sunspot region 3110 and 3112 are producing multiple M-class solar flares every day. Two of these solar flares which took place during the past 24 hours peaked above the M5 (R2-moderate) threshold.

Coronal hole faces Earth, M-class solar flares

Coronal hole faces Earth, M-class solar flares

A transequatorial coronal hole is currently facing our planet. The coronal hole stretches from the solar equator up on to the sun's northern hemisphere. The perfect position for a nice solar wind stream impact here at Earth!
