Coronal hole faces Earth, Sunspot region 2797
Monday, 18 January 2021 14:03 UTC
The northern hemisphere polar coronal hole which has an extension southwards has been facing Earth the past few days. A solar wind stream flowing from this coronal hole is expected to influence our planet in the coming three days. Geomagnetic conditions up to a maximum of Kp4 (active geomagnetic conditions) are possible starting today up till Wednesday (20 January). Solar wind speeds of well over 500km/s were observed last month when this same coronal hole faced our planet.
Sunspot region 2797
New sunspot region 2797 has rotated into view from the south-east limb. We see at least three sunspots and some faculae which could indicate this sunspot region has decayed while on the far side. It is not a candidate to produce strong solar flares at the moment but we will keep an eye on it in case more sunspots start to develop.
