I've been watching it, on the very occasional times we have a break in the clouds! Just on naked-eye now, in dark sky. I've been using Starry Night, but Sky Tonight have a good serviceable finder chart at:

Worth watching, as it will be at opposition on 30 May, at its brightest since 1989 (mag 5.4). Astroman says that 12.5 magnitude Concordia is right near Vesta too (just over 1 degree away ATM).
