Comments: Narrowband filtered photometry centered on the red dust continuum (647nm, FWHM=10nm) shows very similar results to the Cousins R photometry: small gas contamination at this wavelengths. Total magnitude in R is almost 12.2 for a coma diametr of 1.4 arcmin. There is a bent tail almost 1.5 arcmin long in PA230 degrees. Afrho, for both bands, is ranging from ~ 130cm to ~ 280cm for apertures of 50,000 to 13,000 Km (nucleus contribution not subtracted yet).
