The end of the spotless run today. Two regions appearing but only one making the grade (1243 missing out at 323 pixels :). The pipeline looks weak but there are two areas close to the equator on the way.

Day seven spotless for June with the Sun being an almost carbon copy of yesterday. Locarno (SIDC ref station) yesterday recorded a raw value of 45, Wolf would have recorded zero as we did showing the distortion of records that occurs during a solar grand minimum. F10.7 flux falling below 90.

Three groups of specks that will be counted by others not making the grade today. The specks were just visible on my 40mm & 80mm telescopes but definition of penumbra was far from possible. Will we achieve over 6 days spotless for June?

Today is spotless and is the 5th spotless day for June, but there are still 3 days remaining. The June results will be very interesting as the real weight of the Landscheidt Minimum begins to take hold. The F10.7 values also looking weak.

Overall activity dropping a fair degree today. Some of that related to region 1236 approaching the western limb. Region 1240 falling below the threshold with 1241 looking weak. The pipeline also looking weak.

Not much happening today, activity moving down slowly. Australian airports are being hit again with closures due to volcanic ash. More seismic activity during a quiet Sun along with changed jetstreams that funnel the ash northward?

New region 1234 not passing the 24 hour rule and is not counted yesterday or today. We are now into day 3 of a spotless run that many would not expect. In Melbourne we have airline disruption due to ash clouds and New Zealand is having another round of earthquakes.

Once again some groups (1226,1231) displaying large daily shifts in darkness measurement with others remaining consistent. This would imply the images from SDO are good for contrast but begs the question why some groups are fluctuating so much. The Sun is a messy place? SDO not updating at 4:00 UTC today
|
Activity continues it's slide but the ever resilient unipolar groups doing their thing, with more to come looking at Stereo B.
