CaK Full Disk – 24th May 

24 May 17

Despite heading on a journey towards solar minima the suns current geoffective face is quite busy, with bands of activity either side of the solar equator.

AR12659 in Ha – 24th May 

24 May 17

Despite being small, this active region had an interesting amount going on, the single spot was visible faintly on the photosphere, while its bipolar counterpart was seen as a small flaring region.

Twisting Plage – 24th May 

24 May 17

These images of twisted solar plasma are regions of plage, that, in calcium light would show up as white areas on the suns disk.

Sunspot Genesis – 21st May 

22 May 17

It was very clear when I setup and observed on Sunday morning that there was an emerging flux region.

CaK Full Disk – 21st May 

21 May 17

There was quite a reasonable layer of haze when I took this image, but, it was homogeneous, and so the transparency remained constant while I was image.

Dark Filament – 21st May 

21 May 17

Todays filament was a particularly dark one, though, I could not see it in CaK wavelengths.

Active Regions in Calcium Light – 20th May 

20 May 17

There was only a chance for observing the sun very briefly this morning before the heavy showers started to roll in, even then I was cloud dodging and only managed a couple of images in Calcium light.

AR12656 in Ha – 18th May 

20 May 17

Tried a few shots with the HaT before work on thursday 18th May, well I must have been half asleep as I had way too much tilt on the camera and the top left of the frame is clearly out of focus.

Filaments & Flux Regions 14th May 

15 May 17

These are far from the best images, the atmosphere was unstable, but they are a reasonable view of the smaller scale features that were visible on sundays sun, that the 0.2m Airylab HaT does a reasonable job of showing up.

Ha Full Disk – 14th May 

14 May 17

Today was one of those days where it dawned beautifully sunny and clear, and with a weather front passing through overnight the air was very transparent indeed.

CaK Full Disk 14th May 

14 May 17

The sun is pretty quiet at the moment as we head nearer solar minimum, with no sunspots being visible for the 6th day in a row.

Decaying Plage – 11th May 

11 May 17

Quite a difference 24 hours makes on the sun; yesterday ‘ex’ active region AR12655 was a crackling region of plage showing some reasonable feature, today this area has collapsed and is unidentifiable apart from a bit of plasma sculpted by relict …

‘Ex’ AR12655 With The Airylab HaT – 10th March 

10 May 17

The sun was officially ‘spot free’ today with very little in the way of activity, a nod to the upcoming solar minimum.

AR12654 With the Airylab Hat – 7th May 

7 May 17

Far from perfect seeing conditions, but I really like the depth in the plasma in the chromosphere when you start looking towards the lib in hi-res.

AR12655 With The HaT – 7th May 

7 May 17

The tuning was not quite spot on for this image, and it took a lot of attempts to get something worth processing in the less than ideal seeing, but i’m pretty pleased how this came out.


Blog feature
Ha Full Disk – 7th May 

7 May 17

Pretty quiet on this scale on the sun at the moment, a couple of small active regions, a couple of very small filaments and what looks like a old region of decayed plage from a previous active region.

AR12654 in CaK light – 4th May 

5 May 17

Whilst not the largest, or crackling with flare activity there is still plenty going on to see with this active region that developed recently.

Ha Full Disk 3rd May 

3 May 17

Playing with a new setup i’ve been messing around with; i’m frustrated with my Ha full disks of late, my DS PST just sits off to one side of being on band, and if I tune to get on band there are gradients, similar with the DS40 setup, and, the off …

AR12653 in Ha – 1st May 

1 May 17

A bit of a rough and ready image today, it was a bank holiday, so we were sat under a low pressure system, and after the rain of the first frontal band I set up before the trailing front came through and had a go at imaging in the suckers gap.

CaK Full Disk 26th April 

26 Apr 17

It’s that time of year for 3 months where I am able to observe the sun before I go to work in a morning.

AR12651 in Ha – 23rd April 

24 Apr 17

This active region and its associated plage and filaments is framed nicely in its entirety with the Tal100R refractor, Daystar Double stacked Quark, Daystar interference eliminator and the PGR Chameleon 3 with 2×2 binning to freeze the seeing and …

AR12651 Double Spots – 23rd April 

23 Apr 17

A period of better seeing early in the afternoon on sunday allowed me to get another view of this active region with the 0.2m Airylab HaT telescope using the double stacked Daystar Quark, Daystar Interference eliminator and the PGR Chameleon 3 camera …

AR12651 – Swirling Seas of Plasma – 23rd April 

23 Apr 17

I caught a nice fleeting view of this active region through and in between the clouds this sunday morning, the seeing was a little soft, but I think i’ve finally found the best settings for the Daystar Quark on the Airylab HaT.

AR12653 in Ha – 23rd April 

23 Apr 17

A quick grab of this active region not long after it rounded the limb this morning in the brief cloud breaks with the Airylab HaT, Daystar Quark and PGR Chameleon 3 camera.

AR12653 in Ha – 22nd April 

23 Apr 17

Albeit renumbered, this is the second time round for this active region on our star, it appears to be somewhat decayed now with a fairly inactive single spot and trailing region of plage with associated filament material.

Fluffy Filament 22nd April 

23 Apr 17

Taken with the double stacked 100mm Tal100R refractor, this filament really was quite large in size and also quite fluffy too…

AR12651 in Ha – 22nd April 

22 Apr 17

The sky was beautifully blue today with fantastic transparency, alas the wind was blowing from a northerly direction, and with very cold air aloft this meant for terrible seeing sadly.

AR12650 Over 10 Minutes – 18th April 

18 Apr 17

This active region has now been declassified and is not really more than a slightly more active patch of plage.

Flame Prom and AR12650 in Ha – 11th April 

11 Apr 17

The main focus of todays activity on the sun was focused in the north eastern quadrant, with recently rounded active region AR12650, and a gorgeous flame prom on the limb.

AR12648 in Ha – 11th April 

11 Apr 17

This little active region is barely a patch of plage in Calcium light, but in Ha remains pretty interesting! Looks like a wave of plasma washing over it.

AR12648 in Ha – 9th April 

9 Apr 17

The seeing was pretty reasonable first thing this morning, with the solar scintillation monitor recording a steady ~1.5 arc second seeing until about 10.30am before the quality started to fall away pretty rapidly.

New Active Region on The Limb in Ha – 9th April 

9 Apr 17

The seeing was starting to get a bit ropey when I took this image of the new active region that is rounding the suns eastern limb, but it does look like there might be something more to see as it becomes more geo-effective.

Fibrous Filament – 9th April 

9 Apr 17

The seeing was far from perfect when I took this image, but I just thought the filament structure was strangely fibrous in it’s appearance, like it was twisted or knotted.

New Active Region Rounds The Limb – 9th April 

9 Apr 17

Whilst still too early to draw too many conclusions, a new active region rounded the suns eastern limb today, and as this image shows there appears to be a number of small spots and areas of bright plage.

AR12648 in CaK Light 9th April 

9 Apr 17

Despite being designated an active region this area isn’t really more than a patch of plage, and other than a few bright points has nothing that really corresponds with any sunspots.

Tenuous Filaments – 8th April 

9 Apr 17

I love the tenuous fibrils that are visible in this filament that had come around the suns eastern limb on saturday.
