The Dutch Observatory

Today’s session was not good.  I had to image through some clouds which impacted the images, especially the CaK. This resulted in the fact that some artifacts might show.   Another spotless day.  A good sized prominence could be observed at the SE limb, and the NW limb showed some smaller and fainter proms.

Patches of clear skies, with good seeing, allowed a good observing session.  The Sun is spotless today but a few faint proms are visible and a nice filament can easily be made out near the NE limb in Ha.  Today full disk images in the three wavelengths.

Another spotless Sun.  A few proms in the NE, East and the NW.  The Sun is quiet today.

Another spotless day with Very Low solar activity.  The filament in the NW remains, and is starting to approach the NW limb.

Clear skies with good seeing, but no spots to see today.  Solar activity is Very Low.  Some very faint and small proms can be seen around the solar disk as well as a few small filaments, notable in the Southern hemisphere. Did not notice any new reversed polarized areas today.

Clear skies with a spotless Sun.  A faint small prom is visible at the NE limb as well as a small filament in the Southern hemisphere. Other than this, the Sun is quiet.

Clear skies again with a spotless Sun.  I did not notice any filaments or proms.  However, a few small reverse polarized areas, visible as small plages in the CaK image, can be observed in the Southern as well as Northern hemisphere.

The clear skies continue and so did the spotless days.  The Sun is extremely quiet today.  I did not make out any filaments and the proms around the disk did not seem to rise above the “noise” level.  So today only full disk images in the three wavelengths.

Clear skies and a spotless day.  Not much to see on the Sun today.  A very quiet Sun!

Another spotless Sun today.  A number of prominences are visible around the solar disk as well as a few filaments.
