I have been busy working on the new ALPO-Astronomy archive. So now I am catching up with my images captured this month.  The skies were very unstable on March 2nd, but the skies were clear.  Strong wind gusts made the session pretty stressful. However, I still could capture a small active region AR2700  which appeared three days earlier and now was approaching the Western limb. The Active Region Area was at 10 and the spot count at 1.  Today full disk images as well as a close up of AR2700 as well as a nice filament at the Eastern limb and prominence at the SE limb.

Following a cloudy and rainy period, another clear day.  Yesterday a few pores opened in the western hemisphere which became AR2700. In addition we see a few small proms at the eastern and south eastern limb. Total Active Region Area today is 30 millionths with a spot count of 6. Today full disk images as well as a close up of AR2700.

The Sun 2018-02-18.  AR2699 came to an end yesterday so today we are registering spotless day 159. However, the Sun is not completely featureless.  A small filament is visible in the SW quadrant.  Today full disk images and a close up of the filament in Ha.

Another opportunity to capture a few solar images on 2018-02-05.  Following a few days of seeing some pores or small spots and no spots, a new spot came around the eastern limb late yesterday AR2699.  Today’s region area is 80 millionths and the spot count is 1. Today full disk images as well as close ups of the new region.

The Sun on 2018-01-29.  Another spotless day.  Was only able to capture Ha and CaK today.  A few prominences were visible at the SE and NW limbs.

Clear skies with average seeing.  Solar Activity remains Very Low with no flare in the last two days.  In Ha and CaK we still can see the decayed area of AR2696 and a small filament.  In addition we can see a small/faint prom at the SW limb. This is spotless day 147.

Clear skies, but the seeing was poor.  Solar Activity remains Very Low with no flares in the last two days.  AR2696 is decaying fast and today the Active Region Area is 10 millionths while we still had 2 spots.  However at the time of observing I only did record 1.  We still have some filaments and a prominence  at the western limb.

Had to clear some snow before I could start my imaging session today.  Seeing was average.  Solar Activity remains Very Low with no flares in the previous two days.  The pores from my last session evolved into AR2696, which today measures 20 millionths and contains two spots.  A few small filaments are seen today with small prominence on the SW limb.  Images today in all three wavelengths.

Clear skies this morning but cold.  Solar Activity continues to be Very Low with no flares in the next two days. Spotless days continue today with spotless day 146.  More activity seems to be developing including a few small pores to the east of the two filaments near the center of the hemisphere.  In addition there is a nice erupting prominence at the NW limb.

Clear skies but seeing conditions were bad, 1 out of 5, while the temperature was still below freezing during the session. So the resulting images are low quality.  Solar Activity remains Very Low with no flares in the previous 2 days.  We see a pore that developed in the NW quadrant and may become a new named Active Region. We also see a very nice tall prominence at the SE limb a bit fuzzy because of the seeing.  Images today are in all three wavelengths and include the regions mentioned.
