Sol Imaging - December 6th 2022

This morning's Sol imaging.

"The Sun, with all those planets revolving around it and depending on it, can still ripen a bunch of grapes as if it had nothing else to do".  

Galileo Galilei.

Sun dogs over Pembrokeshire.

The cold blue skies of Friday last were greeted with an arrival of a couple of lovely Sun dogs.

These "mock suns" as they are also called hung around for most of the day.  

The sun dogs are produced by a dance between sunlight and ice crystals in our atmosphere.

The ice crystals act like prisms and scatter the sunlight into a colourful light show.

It's been ages since I've have seen such a prominent display. 

The appearance of Sun dogs is not limited just to the winter months. 

One of the best displays I have seen occurred back in 2016 in the month of July.

Moon - Jupiter - Mars - Clouds

MOON

The crescent Moon looked beautiful last night,  a very welcome sight in a clearish sky, but with lurking clouds to the west.

The Newtonian was set up and some afocal phone camera photos were taken.

JUPITER

Around 17:00 the clouds rolled in completely and the sky was lost to astronomers.

I thought that was it for the night, but by chance around 20:00 a gap appeared and Jupiter was ablaze with the promise of that Europa transit I had been waiting for.

Quick set up of the Newtonian and some ten minutes later I had a sketch of Europa crossing the gas giant. 

Once again the clouds were threatening!

MARS

Mars was shining in the east and I trained the telescope onto it.  

It was a bit washed out and lacking in contrast, though I did manage to see the polar cap and some darker detail to the south.

CLOUDS

The ever present clouds finally beat me, by about 20:30 they had bullied their way back to cover the entire sky, the observing was at an end for the evening.

Though considering how persistant the clouds had been last night (and the past week or so!) I'm more than pleased with the results.

Sol sinking into the clouds.

This past week much rain has fallen, and several small gales have come and gone. 

In that time my solar observing had become a game of chance and patience.

This image was taken just before Sol sunk into the hill on the outskirts of our village.

As can been seen in the picture the clouds were just grazing the solar limb.

First 2022 Syrtis Major observation.

I managed to catch a glimpse of the Syrtis Major two nights ago on the 21st at 22h46m UT.

The seeing was terrible, I guess I was lucky to see any of the Syrtis Major outline. 

The North polar cap was evident. 

There was a slightly lighter shading in the Hellas region, though that could have been down to wishful thinking.

Hopefully over the next couple of days seeing conditions will improve.

November 21st 2022 - 22h46m UT - 150mm/f8 reflector

It's Syrtis Major week.

Syrtis Major - 110mm reflector

Syrtis Major, one of my favourite features on Mars will be visible in the evenings of this coming week.

It can easily be seen in most modest telescopes. 

For example my old 4.5 inch reflector and 70mm refractor could both easily see it, albeit a small image.

I've made a chart of the times of possible viewing for the coming week.

The dance of a swirling prominence.

Had to be quick this morning, the streets of fast moving cloud were intent on spoiling my Sol viewing!

After a bit of patience, I was rewarded with a glimpse of a wonderful swirling prominence.

So far it's probably the best dancing prominence I have seen with this little telescope.

I was hoping that the prominence would break in half and form two distinct loops, but unfortunately within the next twenty minutes the structure had notably dissipated.
