Reporta Cristovao Jacques (CEAMIG-REA) a descoberta da primeira supernova do novo observatorio batizado de CEAMIG-REA em parceria com Eduardo Pimentel, conforme comunicado da IAU. "Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION M.S. 18, Smithsonian Astrophysical Observatory, Cambridge, MA 02138, U.S.A. URL http://cfa-www.harvard.edu/iau/cbat.html SUPERNOVA 2004ew IN ESO 153-G17 C. Jacques and E. Pimentel, Belo Horizonte, Brazil, report their discovery of an apparent supernova (mag 17.3) on unfiltered CCD images taken on Oct. 8.18 and 10.15 UT. L. A. G. Monard, Pretoria, South Africa, reports his independent discovery of SN 2004ew at mag 17.5 on unfiltered CCD images taken on Oct. 9.918 and 10.758. Jacques provides the following position for the new object: R.A. = 2h05m06s.17, Decl. = -55o06'31".6 (equinox 2000.0), which is 5".6 east and 12".1 north of the center of the galaxy ESO 153-G17. Jacques adds that nothing is visible at this position on a 1975 red Palomar Sky Survey image, Monard specifying that nothing is visible at this location on a red Digitized Sky Survey to limiting mag 20.5. Monard provides position end figures 06s.16, 32".5. SN 2004ew also is not visible on earlier CCD images taken by the discoverers, with the following limiting magnitudes reported: 2003 Aug.\ 19.33, [18.5 (Jacques); 2004 Sept.\ 8.87, [18.5 (Monard); 12.21, [18.1 (Jacques)."
