Clouds and contrails started moving in.  Another Spotless  day. And today with 37 days, we surpassed the longest spotless streak since solar max. so far. So now we are on the road to the next milestone, the 3rd longest spotless streak from the last solar min. at 44 days. .  Let’s see if we can reach that.  Today is also the 639th spotless day since the solar maximum.  A few filaments in Ha in the Ne and NW and the reverse polarized area is still nicely visible not far from the NE limb.

Well, SWPC did not name yesterday’s area so it remained a pore, and today it’s gone. This means that today we are on the verge of surpassing the previous longest spotless streak during this solar minimum. This is based on SWPCs GEOA reports.  The region that came around the Eastern limb first looked like the negative pole was leading.  this changed during the day when a positive area developed leading the region, now indicating that the polarization is consistent with a C25 area.  The area can still be seen in the images as a faculae in the 540nm image and a plage in the Ha and CaK.

Clear Skies this morning!  Tomorrow would have been the day where the current spotless streak would have equaled the previous longest streak.  However, I did observe a small spot coming around the Eastern limb at a latitude of 22.5 degrees North. So I am afraid that we are coming short again for this and hopes of reaching an Ri of zero for December as well.  The region appeared to have C24 polarization.  So we’ll see if it is stable enough to make it.  We observed two proms as well as two filaments in the NE and NW.  Today full disk images as well as close ups of two proms at the NE and NW limbs.

Clear skies with good seeing.  Another spotless day.  Spaceweather.com reports that today we surpassed the largest number of spotless days of 2008, which was the yearly maximum for the previous solar minimum.  I still keep looking for the long streaks like those in the previous minimum. The current streak stands at 32 days and is maybe on its way to surpass the two previous longest streaks of this minimum at 33 and 36 days. Today the Sun was quiet.  Did not see any filaments but a few small proms around the Eastern limb.

Finally a clear morning again.  The Sun remains spotless.  A few small proms were visible in the NE and NE in Ha.

Clear but cold again today.  The Sun looks pretty much the same as yesterday. A small filament in the Southern hemisphere near the meridian and a few very small proms in Ha.

Clear and cold today.  Another spotless Sun.  A small filament was visible in the Southern hemisphere in Ha. For the rest, the Sun was quiet.

Today we had pretty much the same conditions as yesterday, but more wind and colder.  A spotless Sun with very little activity. Today’s session just for the record.

I had to image through some holes in the clouds again.  The Sun remains spotless.  So today again as usual lately only full disk images.

Today I had to image through holes between the clouds.  The Sun remains spotless.  A small prom could be observed on the SW limb and a filament in the NE.
