J/A+A/444/287 The nuclei of 3 comets (Snodgrass+, 2005) ================================================================================ The nuclei of comets 7P/Pons-Winnecke, 14P/Wolf and 92P/Sanguin. Snodgrass C., Fitzsimmons A., Lowry S.C. =2005A&A...444..287S ================================================================================ ADC_Keywords: Comets ; Photometry Keywords: comets: general - comets: individual: 7P/Pons-Winnecke - comets: individual: 14P/Wolf - comets: individual: 92P/Sanguin - techniques: photometric Abstract: Jupiter Family comets (JFCs) are short period comets which have recently entered the inner solar system, having previously orbited in the Kuiper Belt since the formation of the planets. We used two nights on the 3.6 m New Technology Telescope (NTT) at the European Southern Observatory, to obtain VRI photometry of three JFCs; 7P/Pons-Winnecke, 14P/Wolf and 92P/Sanguin. These were observed to be stellar in appearance. Description: Time series R-band photometry of comets 7P/Pons-Winnecke, 14P/Wolf and 92P/Sanguin obtained with the 3.6m NTT at ESO, Chile, on the 20th and 21st of January 2004. The comets were inactive at the time of observation.
