X2.2 solar flare with earth-directed CME
Samstag, 18 Februar 2023 12:55 UTC
A major long duration X2.28 solar flare (R3-strong) took place yesterday and reached its peak at 20:17 UTC. This is the strongest solar flare of Solar Cycle 25 thus far and we can thank sunspot region 3229 for that. This sunspot region is currently close to the north-east limb and the solar flare was highly eruptive. Despite the region's location near the limb, we can not rule out a glancing blow from this plasma cloud.
X1.1 solar flare
Samstag, 11 Februar 2023 18:59 UTC
After a fairly quiet start of the month the Sun has really started to pick up the pace again. The past few days we have had numerous M-class solar flares from many different sunspot regions. Some of these launched minor coronal mass ejections but most of the time the flares were too impulsive or the resulting coronal mass ejections just weren't aimed at Earth.
An Expansion on Solar Cycle Prediction

Today we have a really special news item for you! We have a guest post made by Christian Harris from Space Weather Trackers. Christian is a friend of the website an has made very well received guest posts before. He has some serious big brain knowledge about everything space weather related. I am sure many of you have heard of him before. He is here to shed some light on the progression of Solar Cycle 25. Please read his article below and gain some fascinating insights on how SC25 is developing. It is well worth the read! If you are interested in Christian's work be sure to follow him on Facebook and follow his Space Weather Trackers Facebook page. Christian, the stage is yours:
Busy Sun! M-class flares and coronal mass ejections!
Sonntag, 15 Januar 2023 13:19 UTC
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
Montag, 9 Januar 2023 19:34 UTC
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
Freitag, 6 Januar 2023 19:16 UTC
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!
Freitag, 16 Dezember 2022 19:55 UTC
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
Montag, 7 November 2022 16:35 UTC
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
Freitag, 28 Oktober 2022 17:36 UTC
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
Montag, 3 Oktober 2022 17:26 UTC
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.
