The Dutch Observatory

The day started with clear skies, but clouds came in and limited my time.  So today only 540nm images.  Since AR2835 is nicely positioned across the meridian, solar granules are nicely visible in this image and one can see that AR2837 is double bridged.  AR2835 has increased to cover 370 millionths, but has not shown any significant flaring.  Neither has AR2836, which produced a C-class flare on the 27th.  A new region has been named AR2837 in the NE quadrant.  Today’s images show the full sun and close ups of AR2835, 36, and AR2837.

As on so many days lately, the clouds rule the sky.  Today’s imaging session was cut short because of some serious clouds.  We now have region AR2835 (Dso, 130 millionths) in the SE quadrant, and this morning the small spots about 10 degrees further south/west of it were named AR2836 (Bxo).  An interesting grouping with very little current activity.  Today, I had to drop the CaK images because of the mentioned clouds.

Rainy and cloudy days are good to do some of the extras.  So I went back to the previous rotation and made a morphology composite of AR2822 from 5/13 trough 5/17.  I am showing the morphology for the 5 days in the three wavelengths in which I capture my images, 540nm, Ha, and CaK. Then, I also did the same for only 4 days of AR2833 from 6/15 through 6/18 and this composite I am showing two wave lengths only, Ha and 540nm.

Another day with great seeing conditions.  AR2833 did develop another pore just North of the spot, which got counted in last SWPC’s night’s statistics.  So we have two spots today.  The other pores are not stable enough to be called out. Full disk images again as well as close ups of the area as well another a little wider Ha close up showing the structure of the filaments and how the plasma streams reach up into them.

Another day with sunny skies and good seeing.  AR2833 seems to be stable but one can see two pores which show in the 540nm close up image.  Is this an indication of activity to come?  Today full disk images as well as close ups of the region and a wider image showing the the Area in relation to the filaments to the East and North-East of the region.

Another clear day.  AR2833 seems to be stable and has not much changed.  It remains the only spot on the Sun.  Today full disk images and close ups of the region.

It has been two weeks since my last observing session.  During that period, SWPC reported one spotless day for June 12th.  However the next day AR2833 came around the Eastern limb and was named.  It covered an area of  140 millionths.  Today it remains the only spot on the Sun as an Hsx.  In addition, a nice prominence was observed at the Eastern limb just a little North of it.  A second prom could be seen at the SW limb.

Clouds kept covering the Sun with little clear areas, so I was only able to capture the 540nm images and the Ha images.  AR2828 has completely decayed to a plage.  while a new area seems to have come around the SE limb. Full disk images and close ups of AR2827 today.
