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.

Saturday evening March 1st was very nice with stable skies.  Larry Owens and I did take the opportunity to make the first JWF image with the new Big-O scope.  1500 out of 3000 stacked in Autostackert2 and sharpened in Registax6.

The Sun is full of active regions today (Febr 28) with AR1990 growing to 250 millionths and 1991 to 280.  Today the sky was also a lot more stable so I am also showing some visible light images made with the SVC80.  Still too turbulent for the C11. Following a full disk image, close ups in Ha and finally 540nm image of the same areas.

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.

The calm after the storm from Friday morning.  The seeing was good at times, and a lot better than in recent months.  Captured 4 complete IRGB series stacked and de-rotated 3 of them while the Great Red Spot was transiting the central meridian.  Each avi 3000 frames and stacked 1000 in each.

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.

The sky was a bit more stable Sunday than Saturday allowing me to make some close-ups of AR1974, 76 and 80 in visible light using the Baader Continuum filter.  (Thanks Stephen for letting me borrow this).  The Ha close-ups were very weak and I’ve not included them.
