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.

A mobile view of the partial solar eclipse.



A misty start to the day, with a steady drizzle of Atlantic rain..!  

It looked as if we had no chance of seeing the partial eclipse. 

Too many clouds in our village, we decided to go mobile.

Telescope, tripod and camera at the ready we headed off towards our local town of Cardigan.

A slight detour had us passing through the village of Boncath, where luckily the Sun was peeking through the mist.

In all, we were able to capture maybe ten images, in a one minute solar viewing gap.

Then old Sol was once again obscured by mist.

Luckily the gap in the cloud coincided closely with the maximum eclipse phase. 

Sol and Luna looked great together, dancing in the misty filtered sky.

Let the Hydrogen - alpha experiment begin.




After nearly a twenty year wait, I finally get my hands on a hydrogen alpha telescope.

It's going to take a bit of fiddling and tweaking to get a decent image, but so far so good.



I managed to take a few very basic afocal camera shots today, crude but with promise!

Also, this daytime solar astronomy lark is handy for topping up the vitamin D levels!


Late evening Aurora.

Last night the Aurora Borealis was visible throughout a large portion of the UK. Here in Pembrokeshire it did not disappoint, though in my c...
