Jupiter sketching under a hazy sky...


I was out observing Jupiter yesterday evening, specifically looking for the Great Red Spot, which was transiting the Central Meridian at about 21h53m UT.

I was in the observatory about twenty minutes before that C.M. Transit, with pencil and paper at the ready.

During the observing session, I couldn't confirm that I saw the GRS, but there was a distinct gap in the South Equatorial Belt, which I figured was most likely due to the paler colouring of the GRS.

It was a  hazy evening with mostly only 1st and 2nd magnitude stars on show...  

By about 10pm the haze and clouds finally blotted out the stars. 

I've a few lunar pictures from earlier in the evening to put on, but they can wait till the next post....

Clear Skies

Love the sketches. For a change you are having better skies than us here in western NY.I think I would like to see Mrs. Pembs in the sketch too!

Thanks Mike.... :0)

The Pembrokeshire skies have been very hit and miss this past week or so.... sometimes only five minutes observing time available....

Luckily I was in the right place at the right time.... though I managed a good half hour Jupiter session at the beginning of the week.... :0)

Yesterday evening the snow finally reached Pembrokeshire... it's all white and bright outside....

Can't wait for the clouds to clear and allow me some clear Jupiter and Moon observing sessions....

Hope your all keeping warm over in NY.....

Pembs..... :0)
