Welcome DSCOVR, Very quiet Sun

Welcome DSCOVR! Yesterday at 16:00 UTC, the NOAA SWPC switched from the Advanced Composition Explorer (ACE) to the Deep Space Climate Observatory (DSCOVR) as the primary source of real time solar wind data. Congratulations to the NOAA SWPC for the successful switch over to their first deep space weather satellite.

Strong M-class flares, Coronal hole faces Earth

A series of strong M-class solar flares took place this morning. Three of them to be precise. All of these solar flares peaked at the M5 class (R2-moderate) or higher.

Two M-class solar flares

More than three months. That's how long it took for the Sun to boost solar activity up to moderate levels again. It was sunspot region 2567 which produced two M-class solar flares early this night. First an M1.2 (R1-minor) solar flare at 00:46 UTC which was quickly followed by an M1.0 (R1-minor) solar flare at 01:49 UTC. These are the first M-class solar flares since the M6.7 solar flare that took place on 18 April.

Slow earth-bound coronal mass ejection

A long duration C1 solar flare from sunspot regions 2565/2567 peaked yesterday around 08:00 UTC. It was responsible for a faint coronal mass ejection that likely has an earth-directed component.

Quiet Sun, Coronal hole faces Earth

Quiet Sun, Coronal hole faces Earth

Five B-class solar flares. That's the only solar activity the Sun managed to produce last week. We're only two years after solar maximum but the Sun has already gone very quiet as if it approaches solar minimum. Could this be a sign for the years to come? We hope not.
