The Dutch Observatory

Yesterday the seeing was great compared to today, so today’s visible light image is not very sharp, but the contours of the spot still look great. This is a prime focus image with the C11 and a WL and continuum filter.

AR2192 produced an X1.0 and an X3.2 flare in the last 24 hours.  Its size has also increased a little to 2570 again.  It seems it does not want to give up yet.  Pretty soon it will be disappearing behind the Western limb and we will have to wait until it comes around again

This is how the region looks through my C11 with a Baader Photo filter and a continuum filter.  This image has been taken with a 0.6x focal reducer in front of the camera in direct focus.

I guess the Sun was waiting for the Solar eclipse to max out AR2192 as it reached 2740 on the 24th.  Today its size went down to 2510, but it produced a X3.2 flare last evening.  The Sun was too low for imaging from my site.  Here a full disk and close up if AR2192 on the 25th.

AR2192 has reached a size of 2700 millionth.  Way bigger than what I’ve seen in the last few years.  The area contains a total of around 55 sunspots (large and small).  This can become a very nice setting for the partial solar eclipse if the weather helps a little tomorrow.

Today AR2192 has increased to a size of 2410.  While I was imaging it produced an X1.6 flare which was directed somewhere around Brazil.  I guess I was lucky as I caught the flare while it as at maximum.  Here an Ha closeup of the action.

I’ve been watching AR2192 as it grew bigger than AR1944 in January.  Over night it grew from 1560 to 2180 millionth.  The Sun spot is huge and producing C and M class flares.  Here a Ha close up under medium seeing conditions.

Catching up with my images from February.   On the 27th the sun showed a large number fo active regions with the largest one being 1982 wgich produced two C class flares and one M class flare in the previous 24 hours.  Seeing was terrible so was unable to make a visible light image.  Today a full disk image with some nice filaments in the southern hemisphere and close ups of the active regions on the eastern and western limbs.

A very clear sky this morning, but the fringes of the jet stream are right above causing fast wind shears, so the seeing was very bad.  However got a decent full disk image with a very nice and long prominence at the Eastern limb and a Ha close up of AR1981,82, and 83, an area that produced today 5 C-class flares and an M-Class.  Too turbulent up there for a 1500mm whitelight with the SVC80.

A sunny morning with temperatures in the 60s and relative stable skies.  A full disk image today and close-ups of AR1974, 76 in h-alpha and filtered visible light.  One image using the 3.8u baader visible light filter and a green filter and the second an additional continuum filter.  AR1974 can still nice be seen as it turns to the backside.  Today it shrunk from 760 to 590 millionth and did not produce a flare at all.
