Intermittent clouds today with seeing conditions below average.  Both AR2767 and AR2768 are somewhat stable.  AR2767 covers 90 millionths while AR2768 covers 20 millionths.  Both regions contain one spot.  It seems from the CaK close up of AR2768, that it is being followed by another C25 polarized region which is just coming around the limb.  Interesting to see tomorrow if that’s true or not.  I used again a 4.6x magnification over the full size image for the CaK close ups instead of the 3x which  I normally use.

A new milestone today!!  This is my 1900st. blog post since I started in 2008.  :-)    In the early days I covered mostly the planets.  Later on I switched to observing. and studying the Sun.  So today we had clear skies, but the seeing was very marginal.   A new Cycle 25 polarized area has come around the Eastern limb.  It contains a small pore and has not been assigned a number yet.  Ar2767 just seems to linger on, while it seems to deteriorate a little.  Today it covers 70 millionths and still has 1 spot.  Today images of the full solar disk and close ups in the three wavelengths of the two areas.  The conditions caused the CaK images to be pretty bad.

Clear skies again for my observing session.  AR2767 has not changed much.  The same statistic prevail, 120 millionths, an Hsx area, and one spot.  Notice the small filament in the NW hemisphere in Ha :-)

Clear skies today but the seeing was below average.  AR2767 remains a stable Hsx spot and covers today the same 120 millionths as it did in the previous days.  Very low activity.  Nothing else that is notable.  Today full disk images and close ups of AR2767 in the three wavelengths.

Clear Skies with good seeing.  The Sun still shows AR2767.  It still covers the same area as the last two days with 120 millionths and it is still a single Hsx spot.  Activity is very minimal.  Today again full disk images and close ups of AR2767 in the three wavelengths.

Yesterday a new Cycle 25 polarized Active Region came around the Eastern limb and was named AR2767.  It covered 80 millionths and it has increased to 120 millionths for today.  It contains 1 Hsx spot which is stable.  Today full disk images and close ups of the new Region.

Another spotless day for the Sun.  However, at least a few small faint proms could be seen at the Western limb.  For the rest it seemed quiet.

I did have a problem with my website where I post my images and reports.  It looks that an entry for the Rotation 2233 was corrupted and I could not access it.  I’ve found a workaround and am posting here the images from July 16, 17, 18, and July 19 of the new Carrington Rotation 2233.  On these four days the Sun was spotless and for the last three days almost nothing noteworthy to mention.  So here are the images of the last three days.

Clear skies with a few clouds streaking through.  Another Spotless day.  Today the Sun is as quiet as I have not seen it often.  No proms, or filaments, only a very small area showing a little activity (plage)  in Ha and CaK.  Could not detect a faculae in 540nm.  It looks like some spiculas or strings of plasma are showing in a half circle extending from the southern part of the area, circling West and North.  Clouds moved through the Eastern portion of my CaK image.  Today full disk images, as well as a close up of the mentioned area.

Clear skies today with good seeing conditions.  No spots for spotless day 797 since Solar Maximum.  However, the Sun stays interesting because it shows some nice prominences.  Today’s SE prominence is even larger and wider today then yesterday.  It measures about 43,000 miles high and 150,000 miles wide.  I wonder if on the far side something interesting is associated with this.  Today the full disk images, as well as a close up of the mentioned prominence.
