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.

Dancing Jet Proms and Coronal Rain – 18th April 

18 Apr 17

Our star certainly is dynamic, this animation spans only 5 minutes, with a cadence of 4 frames a minute.

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.

Surge Prom on the Limb – 8th April 

9 Apr 17

There was a lovely little dynamic surge prom sat on the limb from a active region that had rotated over a day or so before.

AR12648 in Good Seeing – 8th April 

9 Apr 17

It was probably the best seeing i’ve had all year so far, and so decided it was time to get the 0.2m Airylab HaT out for the season and get up close on our star.

Active Regions In Calcium Light – 6th April 

7 Apr 17

The sun was getting low, but using the 80mm scope at 1000mm focal length meant I could keep the exposure short enough to freeze the seeing to get a look at the pair of active regions that we currently have on the face of the sun.

CaK Full Disk – 6th April 

7 Apr 17

Despite the transparency todays seeing wasn’t too bad, and I was pleased to get a shot of the large active region as it headed over the limb.

Ha Full Disk – 6th April 

6 Apr 17

I wasn’t expecting sunshine today, but when I got home from work the sun was out and shining, and despite the haze and contrails in the western sky I got the DS PST out to see what was going on.

AR12645 in CaK Light – 4th April 

4 Apr 17

I was really pleased to be able to leave work relatively early this afternoon and capitalise on the clear skies that had appeared as the day progressed.


Blog feature
AR12648 in CaK – 4th April 

4 Apr 17

Conditions were far from ideal with boiling seeing and poor transparency with all the haze, but using 2×2 binning with the 80mm scope at around 2000mm focal length meant I was able to keep the exposure time short enough to freeze the seeing.

Closeup CaK Quadrant 4th April 

4 Apr 17

Using the 2x barlow to get a little closer in on the active regions on the western limb with the 40mm OTA, homebrew CaK filter and the PGR Chameleon 3 camera.

CaK Full Disk 4th April 

4 Apr 17

Todays disk in Calcium light shows well the active regions associated with this recent up tick in solar activity.

Active Regions and Surge Prominences – 4th April 

4 Apr 17

I knew that AR12644 which was sat directly on the western limb was going to have being putting on a good show as there have been several M class flares coming from it over the past couple of days.

Ha Full Disk – 4th April 

4 Apr 17

The skies cleared slowly during the day, and for once was able to get away early from work.

AR12644 in CaK Light – 2nd April 

3 Apr 17

I really struggled to get a half decent image of this active region on the limb as the seeing conditions were boiling away in between the passing cumulus clouds and their convective instability.


Blog feature
AR12645 in Calcium Light – 2nd April 

2 Apr 17

The seeing was most definitely not in the favour of the larger apertures, but using the 100mm Tal100R refractor stopped down to 80mm using a Beloptik tri-band full aperture ERF, barlowing up to 3000mm focal length and using 2×2 binning on the PGR …

CaK Closeups – 2nd April 

2 Apr 17

Using the 2x barlow on the nosepiece of the PGR Chameleon 3 camera, the homebrew filter with the 40mm scope gave an effective focal length of ~800mm.


Blog feature
CaK Full Disk 2nd April 

2 Apr 17

The sun looked great in CaK light today, lots of activity, including a pair of small spots that have come around the eastern limb.


Blog feature
AR12645 in WL – 2nd April 

2 Apr 17

I tried a close up of the big active region using the 100mm Tal refractor stopped down to 80mm using a Lunt Solar wedge and the PGR Chameleon 3 camera.

Solar Fireworks – 2nd April 

2 Apr 17

This is the busiest the sun has been for some time, with 2 large active regions really putting on a plasma fireworks show.

Active Regions On Our Star – 2nd April 

2 Apr 17

After so long with a relatively blank sun it was nice to see some active regions visible again, and, big ones at that.


Blog feature
Ha Full Disk 2nd April 

2 Apr 17

Clouds on and off throughout the day, but some decent transparency in the gaps; also some decent activity.

Autostakkert3 Beta Version Released 

28 Mar 17

I’ve always been a fan of the ‘Autostakkert’ software for stacking my solar images, it is simple to use, and, IMHO gives good results.

Solar Northern Hemisphere In Calcium Light – 26th March 

26 Mar 17

The suns northern hemisphere was by far the most interesting and most active today, with a new active region forming quite rapidly over the past 24 hours or so.


Blog feature
CaK Full Disk – 26th March 

26 Mar 17

Out of all the images I took today I think my favourite is the CaK full disk, despite the haze, high cloud and contrails this came out really sharp.


Blog feature
Ha Full Disk – 26th March 

26 Mar 17

The sun looked nice in Ha wavelengths today; the proms may not have been large, but there was a lovely emerging active region with rapidly developing spots, and also a large number of small but delicate filaments across the disk.


Blog feature
Sunday Proms – 26th March 

26 Mar 17

The sky was hazy today, and I was struggling to see the proms, so I decided to do an exposure for the prominences alone.


Blog feature
CaK Full Disk – 25th March 

26 Mar 17

Lots of high cloud running through was making imaging difficult and dropping the contrast of the views, but this shot came out ok in the end with a bit of massaging in post processing.

Ha Full Disk – 25th March 

25 Mar 17

I could only observe early today, and when the sun had come across the roof tops the sky was heavy with horses tails cirrus clouds.


Blog feature
Ha Full Disk – 23rd March 

23 Mar 17

Weather conditions were far from perfect with some haze with the sun low in the sky, but with the lack of decent weather so far this year I was not giving up on the chance to observe our star.


Blog feature
CaK Full Disk With A Spot – 23rd March 

23 Mar 17

The full disk is still quiet, even in CaK light, but on the eastern limb a new sunspot rounded the limb; it is small and rather inactive looking, but nice to have a feature on our star.

Equinoctial Full Disk in Hydrogen Alpha – 20th March 

20 Mar 17

The spring Equinox occurred today at 10.28am, the point where the Earths equatorial plane crosses the Suns equatorial plane.


Blog feature
CaK Full Disk – 20th May 

20 Mar 17

Really nice to come home from work this afternoon to a bit of sunshine, even if it was low in the sky, definitely better than nothing! Isn’t it quiet though, normally CaK shows quite bright emitters, but there is very little in the way to see plage …

Setting Sun Through The Haze – 15th March 

15 Mar 17

Today really did seem like spring had finally arrived.

The First Sun In a Month… Ha Full Disk 4th March 

4 Mar 17

Since Christmas the weather has been awful for me, with only a few clear days, normally when i’m at work, this is only my second session of 2017.

CaK Full Disk 4th March 

4 Mar 17

The only real activity on the sun at the moment is in the northern hemisphere, with areas of bright plage.

Bright Spot and a Filament 4th September 

5 Feb 17

The conditions were far from great, but in the depths of winter it is nice just to get an image of the sun as it skirts the roof lines and tree tops of the urban environment.

AR12632 in Ha 4th February 

5 Feb 17

This little decaying active region had very little other than a few plasma rifts going on, and, with a sun heading towards solar minimum is why a scope like the 0.2m Airylab HaT is the way forward.

Chromosphere on The Limb In Calcium Light 4th February 

5 Feb 17

Not really a lot going on on in this image taken in Calcium light of the north eastern limb of our star taken with the 80mm scope at 2000mm focal length with the PGR CH3 and 2×2 binning.


Blog feature
AR12629 in CaK 4th February 

4 Feb 17

While todays seeing wasn’t great there were moments when it showed some promise, to the point I decided to get out the 100mm Tal100R refractor.


Blog feature
CaK Full Disk 4th February 

4 Feb 17

Apart from the decaying active regions that were heading towards the suns limb there isn’t a lot happening on our sun in Calcium light at the moment.


Blog feature
Eastern Prominence 4th February 

4 Feb 17

This subtle little prom on the suns eastern limb had lots of faint detail tucked away that I didn’t realise until I processed the image.
