Sunspot region 2651 remains fairly quiet with only some B-class activity yesterday. It had a small magnetic delta structure yesterday morning but this has decayed leaving not enough magnetic complexity for strong flares. That doesn't mean we should forget about this region as it can still regain some magnetic complexity which would increase the odds of seeing a strong solar flare but for now we should not expect much fireworks from it. But sunspot region 2651 aside, this sunspot region is not our main point of interest in this news article. We have a very familiar solar feature facing our planet right now: a large coronal hole that I'm sure you will recognize from last time around.

Moderate G2 geomagnetic storm conditions were observed this night due to persisting coronal hole solar wind stream influences. Conditions remain favorable for more geomagnetic storming likely up to the minor G1 storm level in the coming hours.

The remnants of old sunspot region 2644 (which was responsible for seven M-class solar flares during the first few days of this month) have now rotated back onto the earth-facing solar disk. It should receive sunspot number 2651 later today from the NOAA SWPC.

A minor coronal hole located on the Sun's southern hemisphere is facing Earth today.

Quiet times. Not a whole lot to report about the past few days but some things caught our attention. A short roundup:
Monday, 3 April 2017 - 21:33 UTC
Sunspot region 2644 was again the most active sunspot region on the earth-facing solar disk today. It produced two M-clas solar flares today: an M1.2 solar flare (R1-minor) at 01:05 UTC and an M5.8 solar flare (R2-moderate) that peaked at 14:29 UTC. The M5.8 solar flare is this region's third solar flare that peaked above the M5 threshold and the strongest solar flare produced by sunspot region 2644 thus far.

Solar activity was at high levels yesterday (2 April 2017) as our Sun produced four M-class solar flares! The strongest of these solar flares was an M5.7 solar flare (R2-moderate) that peaked at 20:33 UTC.

Sunspot region 2644 (N14W60) does it again! It just produced a long duration M5.3 solar flare (R2-moderate) that peaked today at 08:02 UTC.

Not a prank! We just had the first M-class solar flare since November last year!

Sunspot region 2645 has gone Beta-Gamma-Delta! Beta-Gamma-What? Yes, Beta-Gamma-Delta. We give this classification to the most complex magnetic figuration a sunspot region can have: umbrae of opposite polarity in a single penumbra. A sunspot group with a beta-gamma magnetic configuration that contains one (or more) delta sunspots. Let's take a closer look and see if we should expect more solar flares.

|M-class solar flare||1%|
|X-class solar flare||1%|
