Alert Notice 429: Photometry requested for three "Vestoid" Near-Earth Objects

January 8, 2011: Dr. Michael David Hicks (Jet Propulsion Laboratory) contacted the AAVSO requesting precision 
photometry of three solar system objects in support of NASA's DAWN mission to Vesta.  These objects, called 
"Vestoids", are near-Earth objects with similar reflectance spectra to Vesta itself, suggesting they may be fragments 
of that larger body. Broad-band photometry may help constrain object sizes and compositions.
