Abstract (from CDS):
E. O. Waagen, AAVSO, writes that this dwarf nova was reported in outburst by R. Stubbings (Tetoora Road, Victoria, Australia) at visual magnitude 12.4 on Nov. 8.48 UT, confirmed by H. Maehara (Japan) via CCD at V = 13.08 on Nov. 8.630. This outburst is only the third known outburst from this variable (R.A. = 23h25m19s.17, Decl. = -8o18'18.9, equinox 2000.0, from USNO-B1.0; minimum photographic magnitude around 18.5) to have been observed. Previous outbursts of EG Aqr occurred in October- November 1958 (only two known photographic magnitudes, 14.8 and 14.0) and August 1959 (photographic magnitudes 14.0, 17.2, and additional values as it declined back toward minimum). CCD observations now by several observers – including T. Vanmunster (Belgium), T. Krajci (USA), D. Wells (USA), P. De Ponthiere (Belgium), H. Hautecler (Belgium), L. Monard (South Africa), and S. Dvorak (USA) – clearly show superhumps, indicating that EG Aqr is a SU UMa-type dwarf nova; data collected as the superoutburst progresses are being analyzed to determine the superhump behavior and refine the variable classification. All CCD observations reported to the AAVSO may be found on the AAVSO website (www.aavso.org). Charts and photometric sequence information are available through the AAVSO website, as announced by A. Henden in AAVSO Special Notice 24.
