Another clear day with a bit below average.  AR2765 remains calm with not much activity.  Coverage remains at 50 millionth and 1 spot.  Classification also remains as an Hsx area.  Today full disk images as well as close ups of the area in the three wavelengths.

The cold front arrived and the clouds are gone!  Good Seeing today.  AR2765 has turned to the Western hemisphere and shows nice as an Hsx spot. It did not disappear as the other Cycle 25 areas did.  It covers 50 millionths and shows one spot.  A nice filaprom is also visible at the SW limb.  Today I am showing a number of different images of AR2765 and the filaprom.  All wavelengths show the area at its normal size as well as 1.5x using the drizzle function on AS2. In addition, I have added two Ha close up images taken with the ASI120MM camera, which has a pixel size of 3.75 um.

A session this morning was interrupted by some cloud bands but I  was able to finish before the rain came back. AR2765 has turned further onto the visible hemisphere.  It currently measures 100 millionths and has a Wolf number of 12.  Also the plage in the Northern hemisphere is still nicely visible in Ha, as well as the filament in the Southern  hemisphere.  Full disk images today with closeups of AR2765 and the Plage.

A lot of clouds this morning, but I did wait it out and found some holes (more or less).  AR2765 has turned further onto the visible hemisphere and looks nice.  Its classification is an Hsx, shows one spot and a few pores and covers 70 millionths.  However activity seems very low.  A few nice filaments in the South can also be seen.  But the large prom in the NW is gone and a small prom is now visible.  Today full disk images and close ups of AR2765 in Ha and WL as well as close ups of the proms.

We had clear skies again this morning with good seeing.  We seem to have a new area at the SE limb.  Although still close to the limb, I could make out a pore, or spot, in all three wavelengths.   So we will see if this area gets named today.  Today I have full disk images in all three wavelengths, as well as close ups of the new area and the old plage in the NE.

Clear skies with average seeing.  The Active Region that was named yesterday as AR2764 did end the spotless streak, but did not make it through the day as it showed a size of zero at the end of yesterday. This ends the 5th spotless streak during this minimum of 30 or more spotless days.  I could not make out any spots in any of the wavelengths, but the plage is nicely visible in Ha and CaK as well as the faculae in WL.  In addition we do have a nice prominence at the NW limb. An other interesting fact today is that the International Spot number (RI) for May was the  lowest so far in this Solar Minimum with 0.2.  We have seen RIs with 0.5 and 0.4 this minimum, but this is the lowest.  However, it still does not match the RI of zero that we saw in the previous minimum.  Today full disk images, and close ups in Ha of the plage and the prom.

Broken clouds today so I had to image in the gaps between the clouds resulting in poor seeing.  The region that came around the Eastern limb on 5/30 was named this morning by SWPC as AR2764.  The Southern area has not developed any spots yet, but both areas have Cycle 25 polarization.  My close up WL captures today were of very poor quality and did not stack in AS2 nor in Registax, so no WL close up today, but  Ha close ups of both areas.
