Recovery of 107P/Wilson-Harrington = (4015) Wilson-Harrington

MPECs 2009-K24 & 2009-K27, issued on 2009 May 21 & 22, reports our recovery of comet 107P/Wilson-Harrington, obtained over three consecutive nights: on 2009, May 19 and 20 from Mayhill (NM) through a 0.25-m, f/3.4 reflector + CCD (details on image):

and on 2009, May 21, by means of the 0.61-m f/10 reflector + CCD of the Sierra Stars Observatory, Markleeville (CA).

This object has an interesting story, since its cometary nature (a tail without coma) has been reported only once, at the time of its discovery, so its activity appears to be rather irregular:

Also in our current stackings, the object appears perfectly stellar, with no trace of any coma or tail.107P/Wilson-Harrington was last observed on 2007, March 13 by the Mt. Lemmon Survey.
