The Dutch Observatory

It was cloudy this morning, but I managed to get a few images through the holes between the clouds.  Three active regions today:  1176, 1180 and 1183. 

Today I imaged the most active sun this cycle.  A total of 6 active regions were visible.  It looked like someone roughed up the sun.  I wonder what we will be seeing in the next few days.

Today we have 4 active regions: 1176, 77, 78 and 79 with 76 and 78 making a nice rift.  I imaged 75/78 for an hour but nothing noteworthy happend in that time period, so we’ll have to keep looking for something interesting in the next days.  I used one of the images of the hour’s imaging session to show the nice close up of these active regions.

Today AR1176 started to turn further into view, while 1175 approached the western limb and will disappear very soon.

The nice weather continued.  Today I made images in both H-alpha and Calcium-K and made an hour animation of AR1168.  However, I had a terrible time with the alignment of the animation,  so I used one of the images to show a closeup or the nice prominance.

The cloudy skies gave way and provided the opportunity to image the ISS again.  We chose a location off RT11 a few miles south of Charlie Elliott at the intersection with Henderson Mills Rd.  This time we used the SolarMax40 and mounted the camera perpendicular to the vertical axis to get an image that would let us beter understand the information provided in Clasky’s forecasts. Here the image made again by the Frank and Theo Team.

Most of the active sunspots have moved of the earth facing side of the sun, but there still was a lot of activity on the sun today.  Three nice prominances.  The one at the SW limb is whatever is left of the huge CME that many european imagers were able to catch. 

The prominances are still there.  Images with AR1173 and 75 inthe  H-alpha and Calcium-K emission lines.

The prominance visible yesterday are still visible today.  They seem to grow.  Also there are almost no spots left on the sun.  

Ar1169 is moving very close to the Western limb of the sun.  A very large filament can be seen in the Northern as well as southern half of the sun.
