Ha Full Disk 8th August

When spaceweather.com says the sun is blank they need to look in Hydrogen Alpha wavelengths, there is plenty to see here; ex-active regions, plage, filaments and prominences.  The sun is rarely quiet in Ha!  Taken with a pair of double stacked 50mm Lunt etalons, a Coronado BF15 on a 60mm f6 scope with the PGR Chameleon 3 camera.

CaK Full Disk - 8th August

For whatever reason I seem to have been neglecting calcium wavelengths lately, and often as the case here when the sun is blank in whitelight there is still detail to see in CaK, here regions of plage associated with active regions from a couple of rotations ago are still clearly visible.  Taken with the 40mm scope and homebrew CaK filter with the PGR Chameleon 3 camera.

Closing in on Decayed Active Regions - 8th August

Transparency was great this morning alas the seeing had other ideas, and many gigabytes of data were shot in order to get one half decent image.  This active region that first showed itself in June has all but gone now, but there is still a small area of crackling plage, the dark area is not a sunspot but a small surging filament, it was gone minutes later.  Taken with the Airylab HaT with 0.7x reducer and the Daystar Quark and the IMX 249 camera to get this image.

Ha Full Disk - 6th August

The sun is free of spots at the moment but it is not free from activity, a pair of decaying active regions sit mid disk on the solar equator and a filament sits at more northerly latitudes.  There was also a number of small prominences.  This image was taken with the DS50 and PGR Chameleon 3 camera.

AR12717 With The Airylab HaT and Daystar Quark - 5th August

The seeing was far from perfect this morning with passing clouds, however using the Airlylab SSM along with the seeing plugin in Firecapture meant I was able to record only the best ones.  The Airylab HaT and 0.7x reducer was used with the Daystar Quark and PGR IMX249 camera.  This small active region seems to have diminished in activity since yesterday.

Granulation With the Airylab HaT and Daystar Sodium Quark - 5th August

The seeing was pretty rough when this image was taken and was a struggle to get enough decent frames to do something with.  The Airylab HaT, with 0.7x reducer was used along with the Daystar Sodium Quark and PGR IMX249 to give a focal length about 6m.  Just plain old granulation mid disk!

AR12717 With The Airylab HaT and Daystar Quark - 4th August

    Trying something a bit different this morning, I bought a Celestron 0.7x Edge HD reducer to bring the focal ratio back down to f7, something that i've found with my other scopes to offer a sweet spot with the Daystar Quark.  Immediately both visually and also on the laptop screen that contrast was favourable.  The seeing was also not too bad so I decided to rattle off some frames of AR12717.  Overall i'm pleased with this new configuration and look forward to trialling it further when sky conditions are better.  Taken with a PGR IMX249 camera.

AR12717 in Sodium Light

This animation spanning ten minutes shows the rise and fall of solar granules, while the small spot associated with this new active region remains relatively static.  There also appears to be a number of small pores in this active region.  Taken with the ED80, Daystar Sodium Quark and the PGR IMX249 camera.

Ha Full Disk 2nd August

You have to look carefully at the moment as we head towards solar minimum for details on the sun, but today we have a newly designated active region, AR12717.  This has a small single spot with some signs of pores around it.  It is Quite bright in Ha light.  Also visible is a small emerging flux region with signs of the magnetised plasma churning around.  The rest of the disk is essentially blank.  Taken with the double stacked Lunt50 etalons, BF15, PGR IMX249 camera.

New Sunspot - 1st August

This as yet undesignated active region appears to be having a bit of a surge in activity and has developed a small single sunspot.  Whether this will develop any more is anyones guess.  This was taken with the Skywatcher ED80, Beloptik Tri-band ERF, 2.5x barlow, homebrew CaK filter and the PGR IMX249 camera.

Departing Prominences - 31st July

Over the past week or so a region of filaments has slowly marched towards the suns limb, when they reached they put on a great display of prominences for a couple of days too before heading over the solar limb.  This shot was taken with the DS50 and PGR Ch3 camera.
