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!

"Can you speak Venusian"

An amazing array of astronomical eccentrics. 

Or "Independent thinkers", as Sir Patrick Moore used to call them.

Well worth watching on a cloudy evening.

Astronomy typed memories from 2006

 

I well remember taking these observations, the telescope used was a tiny 40mm refractor. 

Even though the telescope was really a toy, it still returned some lovely images of the lunar surface.

Sunspots AR2822 and AR2823.

A quick solar capture from this morning's observing session.  

The Nikon D70 and the Tal1 refractor are a good combination. 

Great to see such a prominent grouping, in the form of AR2822. 

Mars 2020 apparition... A few drawings.

The 2020 Mars apparition has so far  been a bit tricky.  Many nights of bad seeing, and lots of cloudy evenings. 

On the whole I have only been able to capture the odd evening of Mars viewing. 

But those evenings you see above, more than made up for the lousy weather.

Welcome back Mars.

August 9th 2020 : 04h00mUT 76mm O.G. x112 Antoniadi I

Early this morning the world of John Carter, Tharks, Synthetic men and dreamers finally came back to life.

It has been a long wait, at least four years since I last had a decent glimpse of this most wonderful and enchanting of planets.

My 76mm refractor revealed with ease the white bright polar caps, the gibbous planetary phase, a hint of Mare Sirenum, and most interestingly a whisper of light over two small areas of the Tharsis region.

To my mind one of those small light areas might be connected to nearby Mons Olympus, the highest volcano on the martian surface.
Was I seeing the Nix Olympus "The Snows of Olympus"?

I made a quick sketch, said hello to John Carter, and dreamed the astronomer's dream, for maybe another half hour.
The night was now fast giving way to the day, I slowly packed away the telescope, and made a few notes.

This was my first observation of the 2020/21 apparition, the planet was 15.6 arc seconds in diameter.
From now until October, Mars is just going to increase in size.

The next few months are going to be exciting.

Welcome back Mars, you have been sorely missed.

Clear Martian skies

Mark.

Is the climate changing?

An entry from one of my favourite astronomy books "The Stars Night by Night" by Joseph H. Elgie.

This is his journal entry for May 1st 1907!  113 years ago to the day....WOW!

Climate change concern has been around for longer than I thought !


Also note how climate change was apparently an "old, old question" even back in 1907 !
