Today's truly grouse 'Astronomy Picture of the Day' at http://antwrp.gsfc.nasa.gov/apod/astropix.html shows stuff that we newcomers can identify - like Jupiter and the Milky Way. Also mentioned is Vesta, but I haven't a clue to identify it!
I think that I have spotted 4 Vespa. The picture was a great help, but goto RA & Dec, after a bit of Google-ing, was better - unfortunately the bright sky (moon and Melbourne) made things very difficult.
Ended up with three objects in the lens, one central (the likely candidate), but all looking very similar in the conditions. Is there anything special about what we see of 4 Vesta? I'm a bit picky, and would like to be certain that what I think is 4 Vesta really is.
If you are able to image the object, take an image of what you think is Vesta. Then wait a day or two and take another image. Then see if there is any change in its location amongst the stars.
