Sunspot region 2674

Friday, 1 September 2017 - 18:03 UTC

Sunspot region 2674

We admit! We have been ignoring sunspot region 2674 since it appeared on the solar disk a few days ago. It was a large sunspot region at the time with two massive sunspots. It however wasn't all that complicated and there wasn't much of a risk that it would produce a strong solar flare. That changed however during the past 12 hours or so. Keep on reading to find out what sparked our sudden interest in this sunspot region.

M1.2 solar flare, C7.0 solar flare

A new sunspot region is now rotating into view of the north-east limb. It should receive sunspot number 2672 later today or tomorrow. This could be yet another sunspot region with potential to produce strong solar flares as it made itself known this night with an M1.2 solar flare that peaked at 01:52 UTC.

Sunspot region 2670

Wednesday, 2 August 2017 - 16:49 UTC

Sunspot region 2670

Old sunspot region 2665 which caused a couple of large far side eruptions has now rotated back onto the earth-facing solar disk. It has received sunspot region number 2670 from the NOAA SWPC. Due to the activity this sunspot region displayed while it was on the far side, hopes were high for its return. So what is left of this group and should we expect more solar flares?
