Discovery:

E. Beshore  discovered  a comet with a bright, condensed condensation about 20" across and a faint tail in p.a. 270 deg on images taken with the Mt. Lemmon 1.5-m reflector on 2008 may 6.44., magnitude of 13.8. Cometary nature was confirmed by several observers (see IAUC 8941) .  Comet was assigned as P/2008 J2 (BESHORE) via  IAUC 8941 issued on 2008 may 7.  Orbit computation by Hirohisa Sato suggested that the orbit was of short period. The comet was at perihelion at 2.41 AU in late March and has a period of 6.5 years.  It is a member of the "Main Belt Comet" family.

Recovery :

the recovery of comet P/2008 J2 (cf. IAUCs 8941, 8942, 8944) was reported by D.T. Durig of Univ. of South, Sewanee, TN, USA. Comet was recovered on CCD images taken by M. R. Lebow, J. F. North, A. M. Kops, B. B. Goodson, and himself with a 0.3-m f/2.5 Schmidt-Cassegrain reflector (nothing stated about the object's appearance) on 2014 febr. 27.4.

G. V. Williams subsequently identified pre-recovery observations from Jan. 2 obtained by E. J. Christensen at Mount Lemmon. This object was assigned as P/2014 D1 (BESHORE). The comet returns to perihelion 0.3 days earlier than predicted.
