Coronal Holes (Jan 15)

Coronal Hole Stream Incoming

Coronal hole #14 and in particular, the southern extension of CH #15 will begin to face Earth this weekend. A solar wind stream is expected to reach our planet beginning January 17th. Enhanced geomagnetic activity will be possible at higher latitudes. Perhaps some good news for aurora sky watchers.

We Have a Susnpot

Stop the presses! A small sunspot group is now visible towards center disk. This "monster" was assigned AR 2796 and is not considered a threat for strong solar flares. Image below by SDO/HMI.

Visible Disk (Jan 11)

Aurora Watch

An elevated solar wind stream, possibly tied to a weak transient passage led to a surprise period of active geomagnetic conditions (Kp4) at higher latitudes. Aurora sky watchers should be alert during the next 12 hours.

Solar Quiet Continues

The Earth facing side of the Sun remains void of visible sunspots for the 9th day in a row. A few weak plage regions are present, but do not appear too promising. The chance for solar flares should remain very low in the short term.

Coronal Holes (Jan 5)

Coronal Hole Stream Geoeffective

A coronal hole stream containing sectors of south pointing Bz is now moving past Earth. This is helping to disturb our geomagnetic field (Kp4). A minor (G1) geomagnetic storm watch is in effect for the next 24 hours. Aurora sky watchers at high latitudes should be alert during the next 24 hours.

Things Are Quiet

Hello again. Sorry for the lack of updates as of late, things have been very hectic on my side. Nothing really of interest to report on as solar activity has been at very low levels the past week. Region 2794 is stable as it turns towards the west limb and region 2795 is struggling to remain visible. The solar quiet is likely to continue for the rest of the weekend. The new year 2021 should see more and more activity related to Solar Cycle 25, so it's only a matter of time before I get to report about sunspots, solar flares and geomagnetic storms. Happy New Year!
