Hallo,
Der Champagner fliesst im Astrosurf! 
Die elsässische Astroamateurin Claudine Rinner hat vor kurzem den neuen Kometen P/2011 W2 Rinner entdeckt (mag 17,6).

COMET P/2011 W2 (RINNER)
Claudine Rinner, Ottmarsheim, France, reports her discovery of a comet with a 1' tail in p.a. 293 degrees on CCD images taken with a 0.5-m f/3 reflector located at the Oukaimeden Observatory near Marrakech, Morocco (discovery observations tabulated below). After posting on the Minor Planet Center's NEOCP webpage, numerous other CCD astrometrists have also commented on the object's cometary appearance from images obtained during Nov. 29.3-29.5 UT. H. Sato (Tokyo, Japan; remotely using telescopes at the RAS Observatory near Mayhill, NM, U.S.A.) writes that exposures taken with a 0.25-m f/3.4 reflector in bad seeing show magnitude 17.6 without an obvious coma, but with an obvious tail 20"
long in p.a. 275 deg; exposures taken with a 0.51-m f/4.5 reflector show a 13" coma and the same tail dimensions. R. Ligustri (Udine,
Italy) also used a 0.25-m f/3.3 reflector remotely at the RAS Observatory near Mayhill to find a coma elongated toward p.a. 270 deg (size 33"). E. Guido, G. Sostero, and N. Howes write that stacked images taken remotely with a 0.25-m f/3.4 reflector at the GRAS Observatory near Mayhill show a diffuse coma nearly 15" in diameter. J. V. Scotti reports that images taken with the Spacewatch 1.8-m f/2.7 reflector (+ Schott OG-515 filter, spanning V + R + I; pixel size 0".62) shows a diffuse coma of diameter 7" with a tail extending
0'.30 in p.a. 289 deg. G. Hug (Scranton, KS, U.S.A., 0.56-m reflector) notes a broad tail extending 1' in p.a. 285 degrees.
