Sol imaging: 22nd August 2021

 

  

 16h 15m UT -40mm PST/Samsung S6

 

I've not seen old Sol for going on nearly a week!  Lots of slow moving clouds had put pay to any observations.

This afternoon the blue skies prevailed and I was able to capture a few images.

 

I wanted to give an impression of the full solar disc and also capture the several small prominences that were visible.  

After a bit of fiddling with an image I settled on the picture you see here. 

 

 

Not the best image; that is obvious, but it does clearly show several of the prominences and their positions.

 

The white dots seen on the surface are some processing artefacts I couldn't delete.   

The program used to process the images is GIMP 2.8

Imaging and photo processing does not come easy to me, I would prefer pencil and paper, but today I thought I would try my hand at a bit of digital photo editing.  

Here's the final Ha Sol image capture:

 

First clear Sol image for a week.

Wow... it's been a week since I was last able to image the Sun! 

The weather these past seven days has mostly been rainy and cloudy. 

Or alternatively cloudy and rainy, depending on how you look at it!  

This afternoon the Sun came out, and all was forgiven in an instant.

I took my time observing those two beautiful prominences. 

They were so delicate, wonderfully tenuous, definitely ethereal.

Today's solar activity - 30/06/21

Plenty of solar action this morning, AR 2835 has a wonderful plage display snaking its way around the region. 

Also there are a few filaments, which can be just seen in the pictures, but easily spotted with the naked eye.

The Sun here is hot today, though nowhere near as hot as in some parts of the world.  

My thoughts are with  the people of the Pacific North West, who are experiencing temperatures as high as 46 Celsius at the moment !  

June 22nd 2021 Hydrogen Alpha light.

 

A couple of prominences today, plus a very noticeable long filament, with sunspot group 2833 close by. 

Seeing not good, and overall solar contrast low.

Difficult to pull out any detail with the IrfanView software.

Summer Solstice in hydrogen alpha.

 

I had a quick sol peep this morning, but not much prominence activity, as the above picture shows. 

Skies were pretty well clouded out for the whole day.

Did manage to spot a lovely dark filament, though unfortunately failed to capture it on the camera. 

Maybe tomorrow I will have better seeing conditions..... you can't win them all   :-) 

Happy Solstice...

Today's prominences.

Blue skies, fledgling sparrows chirping, hot concrete underfoot, a perfect day for soaking up the hydrogen alpha light.

Those sparrows aren't half noisy at the moment!  A Harley Davidson just thundered by... one day !

Through the white light filter AR2833 stands out beautifully; it looks like a tiny island surrounded by a vast ocean of clear cool water. 

Through the Ha filter AR2833 looks like an island surrounded by seething magma seas, swirling  fire storms, and  violent hurricanes.... Which I guess it is. :-) 

Bare warm feet on Sun drenched concrete.. you don't get that observing in the night time !

  

Tweaking the hydrogen light.

Out of the past ten days, I've managed to observe for five days. Which isn't bad considering the cloud cover so far this month.

This past week I've spent most of my observing time fine tuning the PST's etalon, and also importantly  looking for that "sweet spot" in the telescopes field of view.

Glad to say, that after much tweaking and head scratching , the etalon positioning and "sweet spot" have now been sorted out.

What started off as a red bland blob with a little indistinct prominence poking out of it a week ago, has now been transformed into a seething mass of prominences, filaments, plages, sunspots, and spicules.

The PST is a wonderful little solar scope, I admit it requires some etalon and sweet spot tweaking for best results, for me that is part of this little telescopes charm.
