Solar Activity 29th May 2020

Not much today....
A couple of small proms, but an interesting line of filaments in the north west.
There's also, what looks like a new AR close to the SE edge.
Images to follow.

G'day Ken
Have been reading that there have been some B class flares just over the NE limb yesterday. Possible sunspot / AR coming around in the next few days.

On May 29, 2020, a family of sunspots — dark spots that freckle the face of the Sun, representing areas of complex magnetic fields — sported the biggest solar flare since October 2017. Although the sunspots are not yet visible (they will soon rotate into view over the left limb of the Sun), NASA spacecraft spotted the flares high above them.

The flares were too weak to pass the threshold at which NOAA's Space Weather Prediction Center (which is the U.S. government's official source for space weather forecasts, watches, warnings and alerts) provides alerts. But after several months of very few sunspots and little solar activity, scientists and space weather forecasters are keeping their eye on this new cluster to see whether they grow or quickly disappear. The sunspots may well be harbingers of the Sun's solar cycle ramping up and becoming more active.

Or, they may not. It will be a few more months before we know for sure.

The intensity of this flare was below the threshold that could affect geomagnetic space and below the threshold for NOAA to create an alert.

Nonetheless, it was the first M-class flare since October 2017 — and scientists will be watching to see if the Sun is indeed beginning to wake up.
