VizieR Online Data Catalog: r'-band photometry of comet 96P/Machholz 1 (Eisner+, 2019)
Abstract
Images were obtained on a total of nine nights during the 2017/2018 apparition, primarily using the broadband r' filter. The observations were always tracked at the ephemeris rate of the comet, with the exception of the images obtained on 2018 July 11/12 with the New Technology Telescope, which were taken with sidereal tracking and short-enough exposures to prevent the comet from moving more than the seeing disk. Images taken on 2017 April 7 were obtained using the 4.2 m Southern Astrophysical Research (SOAR) telescope on Cerro Pachon in Chile using the Goodman Spectrograph Red Camera, which utilizes an e2v 231-84 CCD (Clemens et al. 2004SPIE.5492..331C). Images taken on 2017 July 2 and 3 were obtained at SOAR with the SOAR Optical Imager (SOI), which uses a mosaic of two e2v 2048x4096 pixel CCDs (Walker et al. 2003SPIE.4841..286W). The observations on 2018 June 25 and July 10/11 made use of the Goodman Spectrograph Red camera at the SOAR telescope. Snapshot r'-band images were obtained on 2018 July 12 using the 3.54 m New Technology Telescope (NTT) at La Silla, Chile, with the ESO Faint Object Spectrograph and Camera (EFOSC2), which employs a 2048x2048 pixel Loral/Lesser CCD (Buzzoni et al. 1984Msngr..38....9B). Our final images were acquired using the 4.2 m William Herschel Telescope (WHT), in La Palma, Spain, on 2018 July 31 through August 2.
