17th January 2018, 0500-0600+. I arose early this morning to let the cat out and make a cup of tea and discovered that, although it was cold and windy, the sky was clear. Looking out of the west-facing front-room window, I noticed Regulus (alpha Leonis) and Algieba (gamma) and using the Helios 6.5x32 bino and 15x50 monocular decided to see if I could locate CERES. By plotting its RA and dec on map 74 of Uranometria, I worked my way to mu, 22, epsilon
and to Alterf (lambda) and up to kappa. Above that found a wide faint group (rather resembling the "Keystone of Hercules" or the "top part of Orion") of faint (7th to 8th magnitude stars) and then across to the right there was hardly any stars shown on the map,with the exception of four faint stars straddling the Leo - Cancer border. One of these turned out to be CERES! Re-checked various sources to confirm the identification. Most sources suggest that it is just about magnitude 7. In a few days it will be across the border and in Cancer. regards maf

18th January 2018, 0600-0615. Cold & windy but clouds mostly cleared. Used 15x50 monocular through the west-window class as yesterday. Immediately found the field-stars and CERES. Ceres had moved noticeably towards the left-hand star of the triangular-asterism and nicely confirmed my identification ! regards maf

18th January 2018, 2155-2245: Very clear sky. Used Acuter DS65 at 12x and 19x, from the back garden. Very good view of the starfield wih many much fainter stars seen and CERES.

19th January 2018, 0540-0615: Used Acuter DS65 again at 12x and 19x but through the window-glass. CERES well shown.

19th January 2018, 2120-2125: Rather poor conditions low-down and rain predicted for later, so before bed, used Endurance 12-36x50 spotter on a table-top tripod through the bedroom window glass, to pick out CERES rising. Soon located with some movement from previous noticed. (NB. Glade I grabbed the chance, as in the pre-dawn of Saturday it was raining!!)

Interesting to read your observations Mike. I meant to have a look for Ceres this evening, and it slipped my mind. Do you keep a plot of the path of objects like this in your copy of Uranometria?

Best wishes, Jeff.

I plot in pencil and eventually after a current series of observations I rub them out. Some tracks may get left for a while I often copy the tracks in my astro-diary. regards maf

Mike, I've had some very clear skies here this evening, and have been able to make an observation of Ceres. I've attached a plot of the surrounding stars that I could see in the 8x56. Ceres is shown at centre in the field of view. Sigma 2 Cancri is near the top and Tau Cancri at the bottom. Ceres was just on the edge of visibility for me. The sky transparency was good. I'll see if I can continue observations over the coming weeks.

I spent a bit of time scanning around the night sky afterwards. I'd forgotten how impressive the Beehive Cluster (M44) is. Light pollution does hamper my view, but this evening I could just make out M37, M36 and M38 in Auriga, which is a good sign. Quite often I struggle to make them out. Very peaceful to have some time sitting under starry skies.

Best wishes, Jeff.

I've made another observation of Ceres this evening, and had a go at plotting the surrounding stars, as viewed in an 8x56 binocular. I think it's moved a little over a degree since my last observation on the 9th Feb.

The outside thermometer was showing 2.5 degrees Celsius this evening, but it actually felt a lot warmer. Good to have some clear skies for a few hours from sunset onwards.

Best wishes Jeff.
