Yesterday we saw the return of old sunspot region 2172 on the solar disk which is now numbered as sunspot region 2192. Sunspot region 2192 looks very big but it wasn't that active until this morning when a moderatly strong M1.6 flare erupted.
The M1.6 flare was not eruptive, no CME is expected from this event. Even if there was a small coronal mass ejection (CME) accompanied with the event, due to the position of this sunspot region near the limb, it won't be Earth directed.
Sunspot region 2192 looks big but it is surely not the biggest sunspot region of this cycle. It has a very large central leader spot which makes it look impressive. Now that sunspot region 2192 is fully into view, we can see it's magnetic layout better and judge it's flaring potential. The leading group of spots with the large umbra contains one delta spot in the western part making it a beta-gamma-delta region which has the capabilities of producing a strong flare. From the short period that it is in view it looks relatively stable. The large amounts of faculae around the region is a soup of crumbled penumbral area with a few tiny spots in it; those two tiny spots have an opposite polarity (a delta spot).
