Hi All,Looking for some northern hemisphere help in confirming a probable newcomet in SWAN. Here are raw pixel coordinates and corresponding,approximate RA/Dec values:Date X Y R.A. Dec---- ----- --- ------- -------6/07 353 202 11h 34m +53 30'6/10 355 208 11h 22m +51 00'6/12 357 214 11h 10m +48 30'6/13 358.5 217 11h 03m +47 30'6/14 359 221 10h 59m +45 30'6/17 362 224 10h 47m +44 30'The last two coordinates are admitedly a bit inconsistent withthe trend, which could be partly explained by epoch time differences,or the last coordinate could alternately be:6/17 360 226 10h 53m +43 00'Brightness not much above the limit for SWAN -- perhaps in the12th magnitude range? --Rob
