Right now Ceres is in a really easy spot to find, and in fact I was able to view it through 8X40 binoculars last night! I wanted to get a view through my telescope, but by the time it rose enough to see from where my telescope was stationed the clouds had rolled in. If you have never seen this minor planet, take a look once Scorpius has risen. Find Acrab (Graffias), the Easternmost claw of the scorpion. Just to the E are three nearly identical ~4 magnitude stars in a nearly North/South line. Find the small triangle of nearly identical ~7 magnitude "stars" in the middle of the two "top" stars (top meaning Northernmost). The Northernmost "star" of the little triangle is Ceres. 

 

Although this "triangle" of ~7 mag stars was nearly equilateral last night, it is now more isosceles and will become a neat straight line by Sunday night.

 

I've seen Ceres before, but it was quite a while ago and not so easy to find.

Thanks for the head's up; I'll look the next clear night.

 

Never saw Ceres before.

I observed 1 Ceres at opposition six hours after opposition this morning at 0500 UT ( 1:00 AM local time 29 May) with my 12x36 image stabilized binoculars.  Magnitude 7.0 Ceres formed a triangle with phi and chi Oph about 4.5 degrees east of Graffias in Scorpius.  I hope to make another observation soon recording the movement of Ceres and confirming my observation.

Looking forward to seeing it again tonight with the telescope. Have had clouds or unable to get out lately, so I'm curious to see the change in position.

The dwarf planet/asteroid 1 Ceres (magnitude +7.0) reached opposition in western Ophiuchus on May 28th.  Ceres retrograded into Scorpius shortly thereafter.  A finder chart can be found on page 48 of the May 2019 issue of Sky & Telescope.

I got to see it Thursday night with my 8” SCT and 3” Tak.  Very nice views as it appeared to have a slightly yellowish tint to it.

I made a couple of observations of Ceres recording its movement as it moved out of Oph into Sco.  Report and sketch here.  smile.gif

On Monday night, I observed 1 Ceres in Scorpius using my 15x70s and 10" f/4.7 Dob at a dark site.  The highest magnification I employed was 240x, which was not enough for the dwarf planet to appear as a disk.

Moving right long, isn't it?  smile.gif 

 

Aquarellia  saw the disk at 833x with his 10" scope--he made this drawing.
