6 Minutes in the Life of AR12665 – 8th July 

8 Jul 17

The seeing was just about holding up for the 100mm of aperture of the Tal100R refractor this morning so I decided to go for an animation to see what this active region was up to.

AR12665 With HaT in Poor Seeing – 8th July 

8 Jul 17

I started off imaging with the 203mm Airylab HaT this morning, but the seeing was awful, and after shooting about 20 file runs this really was the best of them (and it’s not very good!), so rather than pursuing this fruitless avenue I decided to back…

Glorious Proms – 8th July 

8 Jul 17

A lovely great big prominence visible this morning on the suns eastern limb.

New Active Region Rounding The Limb – 5th July 

6 Jul 17

Despite having to shoot through haze and ramp the exposure up, it was very easy to see just how dynamic this crown of plasma was as it spitted and changed form in real time on the laptop screen.

The Scars of Spots Long Gone – 5th July 

6 Jul 17

This may seem a fairly insignificant bit of the sun, but with its plage and filamentary structures marking magnetic fields, this area is the relic cores of some of the active regions that we have seen in the past couple of months.

CaK Full Disk – 24th June 

24 Jun 17

An unexpected break in the clouds first thing allowed me to grab a quick CaK full disk this morning on a day when the forecast was for wall to wall clouds.

AR12662 with the Airylab HaT – 18th June 

19 Jun 17

This is my favourite image from the weekend and also one of the sharpest, taken with the 203mm Airylab HaT at a focal length of 7 metres, it is really starting to pull in some of the finer details caused by the magnetic field lines and their …

AR12663 with the Airylab HaT – 18th June 

19 Jun 17

This angry little active region has been crackling with a number of smaller spots between the main bipolar group with many lines of swirling plasma molded by magnetic field lines.

Plage with the Hat – 18th June 

19 Jun 17

This region is typical of the sort of small scale features on a quiet sun that can be seen with the 8″ Airylab HaT; with a regular size scope there would be little to see, but at nearly 7m focal length there is quite a bit.

Dark Filament – 18th June 

19 Jun 17

This filament looked particularly dark on sundays sun, and I was pleasantly surprised when I looked at the final image the subtle detail that had been recorded.

Active Regions with the Tal100R – 18th June 

19 Jun 17

The 100mm Tal100R was putting on a good show with sundays solar activity as the heat of the day became too much for the seeing for the Airylab HaT, and with the wider field of view and lower resolution the resultant images were still nice and sharp.

CaK Full Disk 18th June 

18 Jun 17

With temperatures up at 28c when I took this picture, the 40mm scope was all I was going to be able to use in the midday heat with the seeing conditions boiling away.

AR12663 in Ha – 17th June 

18 Jun 17

This is only quite a small region on the sun, ‘merely’ a dozen or so Earths across, but with the 0.2m Airylab HaT at nearly 9 metres focal length it is possible to get up close and personal with this tempest of plasma.

AR12662 in Ha with the Airylab HaT – 17th June 

18 Jun 17

These 2 shots were both taken with the Airylab Hat, double stacked Quark, and PGR Chameleon 3 with 2×2 binning, the only difference being the wider field view used the Baader 0.7x solar telecompressor to give an effective focal length of just over 6 …

Solar Activity in Ha with the Tal100R Refractor – 17th June 

18 Jun 17

I have found a bit of an unusual setup that I quite like in this years solar season; my trusty 100mm Tal100R refractor works particularly well when my double stacked Daystar Quark is used in conjunction with the 0.7x Baader solar telecompressor and …

Ha Full Disk – 17th June 

18 Jun 17

In the absence of an ‘in one’ full disk setup that i’m currently happy with it means it has been a while since I got an overview of our star at 656nm.

AR12663 in CaK – 17th June 

18 Jun 17

This is by far the most active region on the sun at the moment, with it’s trailing wake of plage.

AR12662 in CaK – 17th June 

18 Jun 17

A couple of shots of this solitary spot and its associated active region taken with the 100mm Tal100R telescope stopped down to 80mm with the Beloptik tri-band, and, using the home brew CaK filter and the PGR Chameleon 3 camera.

AR12661 in Ha – 4th June 

4 Jun 17

This active region that has rotated into view only recently spewed off a near M class flare in the hours precedingthis image being taken and looked to be very lively at the time, with lots of swirling plasma, and, in this image taken with the double …

CaK Full Disk 25th May 

28 May 17

The active regions of the past days are slowly starting to rotate out of view as can be seen in this full disk taken with the 40mm scope at 500mm focal length with the PGR Chameleon 3.

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.

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 …

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.

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.
