The Spring Equinox Sun.  Clear Skies and the Jet Stream retracted to the great lakes area giving us good seeing conditions.  Solar Activity remains Very Low.  Another Spotless day.  A few nice filaments are visible in Ha, and the WL images again show granulation! Some nice and faint prominences, but too small and dim for the SM40.

After a few days of clouds and rain, clear skies again with good seeing.  Solar Activity remains Very Low.  No Active Regions, and this is so far the longest stretch of spotless days.  Today is the 60th day since Solar maximum and number 13 since the last spot was seen.  The Sun shows some nice filaments in Ha and CaK  and WL even show some interesting areas.  Full disk images today as well as close ups in the three wavelengths.

Clear Skies with seeing conditions a little better than yesterday. The jet stream has moved to the East but still leaving some remnants.  Solar Activity remains Very Low and the Sun does not show any Sun spots today either, bringing the spotless days to 57. Two nice filaments are visible in Ha today and a very small prom at the NE limb. Some small plages can be seen in CaK.   Today full disk images and a few close ups.

Clear skies but windy, and what was worse, a 130mph jet stream above causing bad seeing.  A spotless Sun again today (day 56). Full disk images showing some nice filaments in Ha and some plages in CaK.  I tried to image the faint and small proms at the NW limb, but the seeing conditions would not let me get the contrast I wanted.

Before the clouds arrived: Clear and transparent skies with average seeing.  Solar Activity remains Very Low.  The spotless sun continues today with day 52.  In WL the sun appears completely blank, but in Ha and CaK some interesting filaments and areas are visible, as well as a few proms. Today full disk images as well as close ups of the mentioned regions.

Transparent and clear skies today with good seeing! Another spotless day. (Day 50)  Solar Activity remains Very Low.  Today full disk images as well as close ups of the East and West limbs of the Sun.

After two days of clouds and rain clear skies with good transparency and average seeing.  No Sun spots today and yesterday.  That makes today the 49th spotless day since solar maximum and continues the solar activity of Very Low.  Today full disk images as well as some close ups of the W and E limbs of the Sun with some interesting plasma activity in the West Quad image near the limb.

Clear and transparent skies this morning with average seeing.  The jet stream did move on for a few days.  So, we had to have another spotless day.  This is the 47th spotless day since Solar Max.  Despite this, some pores were still visible in WL and some plages remained.  Solar Activity remains Very Low with no flares in the last two days.  Full disk images and finally a few close ups of higher quality than the last weeks or months.

Clear and very transparent skies, but the seeing was bad. Still three Active Regions today with a total Area of 100 millionths, and the spot count is at 6.  With the given seeing condition it is hard to make out any region in WL.  In Ha and CaK one can see the plages.  Images today of the mentioned regions as well as full disk images.  Also the ALPO gallery site is still affected by the network outage of a section of the Amazon cloud.

Clear skies with strong winds, and wind gusts up to 35 mph, making the seeing bad.  Solar Activity remains Very Low with no flares in the last two days.  Four active regions remain while AR2638 is turning rapidly to the Western limb.  Total Active Region Area for today is 120 millionths and the spot count is at 12.  Images today in the three wavelengths.
