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.

Nevertheless, with an active Sun comes a lot of flaring activity! Most of these solar flares were not associated with obvious earth-directed coronal mass ejections. There was however one eruption from sunspot region 3182 (first partial halo coronal mass ejection in the video below) which does have a chance to pass our planet as a glancing blow late on 18 January. Active to perhaps minor storm conditions should be expected if this cloud passes our planet. The second coronal mass ejection (CME) in this video came from an M6 solar flare this night at 03:42 UTC but it is expected to miss our planet.

Live northern lights stream on YouTube

Did you know we are also on YouTube? We occasionally stream live from Kiruna, Sweden and last Friday we did just that. We had clear weather and some nice enhanced geomagnetic activity which resulted in some amazing aurora up in Swedish Lapland. Check out a replay of our stream in the video player below. Skip to about 23:00h local time for how a real sub storm looks like around the arctic circle!
