Check it out, the Hubble Space Telescope (as I had hoped) has taken new images of the asteroid 4 Vesta in order to assist Dawn before its arrival there later this year. Though naturally still quite fuzzy, the new images are of great assistance for the probe as the video (and this news release) explains.
Apparently Dawn will begin using imagery of its own of Vesta to commence the final approach around April or May (three months before arrival) so we might see some low-res photographs taken by the probe then, and resolution will improve over that of the HST about a month before arrival. Current distance to Vesta is now only about 20 million km.
