[vsnet-alert 5044] RE: 1432-0033 is a new UGSU dwarf nova



Please note there's an error in the coordinates I listed for this object. The coordinates I quote (14h32m25.88s, -00d33'00".9) are actually B1950, not J2000. The object is listed as Vir4 in the Downes, Webbink and Shara catalogue, at J2000 coordinates 14 35 00.14, -00 46 07.0.

Regards,
Tonny

Thanks John, for pointing this out !
