The Dutch Observatory

Clear skies just before the clouds came in for the next storms, and just enough for an observing session.  It looks like the old AR2760 shows some pores again and a new area with a pore shows in the NW quadrant. The second area from yesterday was named for a short period of time as AR2761 but then downgraded as a plage and did not make it in the daily summary.  (This is similar to AR2752).  Maybe ready for two named Active Regions tomorrow, but it will be cloudy here.  Today full disk images as well as close ups of the mentioned regions.

Clouds gave way to clear skies with relative good seeing.  AR2760 is still visible and the pores from yesterday have now been named AR2761 this morning.  However during my observing session it was not visible in continuum, and only visible as a plage in Ha and CaK.  I tried some higher magnification today on both areas in Ha.  Today full disk images and close ups of the two regions.

Clear Skies with average seeing this morning.  AR2760 has now 4 spots and still covers 10 millionths.  Another pore has appeared just West of the Meridian in the Southern hemisphere.  Two pores can be seen in the images.  Today full disk images and close ups of the regions in the three wavelengths.

Clear skies today but very windy and unstable seeing.  The pore from yesterday has increased and is now named AR2760, covering 10 millionths. It also seems to have developed a following spot.  We also can see some small light bridges crossing the spot in 540nm.  This marks the end of the current spotless streak of 20 days.  The faint proms from yesterday are nicely visible today.  Full disk images and close ups of the mentioned regions.

The clouds started to break, but the observing session was a “cat and mouse game” to find clearances between clouds.  But I managed to get the full disk images as well as some close ups in all three wavelengths.   However the seeing conditions were not good.  Today’s Sun is spotless but showed a small pore in WL and a small plage in Ha and CaK.  No region number has been assigned to it.  Today full disk images as well as close up of the region and a few faint filaments to the North.

A few wispy clouds and some contrails tracking through.  A spotless Sun again.  The nice prom from yesterday has rotated onto the visible hemisphere and only left two very small proms visible today.  In addition, the filament is hard to make out today.  A real quiet Sun today.

Clear skies with average seeing.  The Sun is spotless today for spotless day 16 in the current streak and spotless day 19 of the current rotation.  A small but distinct filament in the North near the meridian, and some nice proms at the NE and the Eastern limb.  Today full disk images and a close up of the filament and the NE prom.

Another spotless day with fast moving clouds impacting the observing session.  Not much happening today.

High and fast moving cirrus clouds but good enough for some images.  The Sun is spotless again today with only a very small prom in the SW and a small filament in the SE.

Clear skies with good seeing. The Sun remains spotless today. I noticed some proms at the SE and SW limbs. However during the processing of the images it showed that the SE prom was erupting, which is visible in the full disk Ha image. Too bad I did not notice this during the observing session, in which case I would have made a close up.
