COMET C/2013 V5 (OUKAIMEDEN)
     An apparently asteroidal comet discovered by Michel Ory on CCD images
obtained with a 0.5-m f/3 reflector at the Oukaimeden Observatory, Marrakech
(discovery observations tabulated below), and posted on the Minor Planet
Center's NEOCP and PCCP webpages, has been found to show cometary appearance
by CCD astrometrists elsewhere.

Fifty-eight stacked 30-s exposures taken remotely by E. Guido, N. Howes, and
M. Nicolini with an iTelescope 0.43-m f/6.8 astrograph at Siding Spring on
Nov. 12.6 UT show a diffuse coma about 10" in diameter of red mag 18.4-18.5.
L. Buzzi (Varese, Italy, 0.60-m f/4.6 reflector) finds a condensed coma 10"
wide, elongated in p.a. 320 deg, on images taken on Nov. 13.1.  Sixty stacked
20-s images taken by R. Holmes (Ashmore, IL, USA, 0.61-m f/4.5 astrograph;
measured by L. Buzzi and three others) on Nov. 13.4 show an obvious round coma
8".9 in diameter with a broad tail 11".1 long in p.a. 279.2 deg.  Peter
Birtwhistle (Great Shefford, Berkshire, England, 0.40-m f/6 Schmidt-Cassegrain
reflector; Nov. 13.2) found the object to appear essentially stellar but
slightly softer on the western side, with a possible faint extension 9" long
in p.a. 285 deg.  H. Sato (Tokyo, Japan; remotely with an iTelescope 0.51-m
f/6.8 astrograph; Nov. 13.7) writes that eight stacked 60-s exposures show a
strongly condensed coma 15" in diameter with a faint, fan-like tail 25" long
toward p.a. 300 degrees; the luminance-filter magnitude as measured within a
circular aperture of radius 8".8 was 18.3.  Sixty stacked 60-s taken by
Holmes with a 0.81-m f/4 astrograph on Nov. 14.4 (measaured by S. Foglia and
six others) show a round, compact coma of diameter 8" and a wide tail 12" long
in p.a. 295 deg.

     The available astrometry, the following parabolic orbital elements by
G. V. Williams, and an ephemeris appear on MPEC 2013-V95.
