V2573 Oph: Vello Tabur's early images Dear Colleagues, Vello Tabur kindly presented early images of the field V2573 Oph on his webpage. My own examination: May 4 image: there looks like to be a postively detected object near the nova, but the marked pixel seems to be about 1 pixel too east from the expected position of the nova (could someone confirm?). This positional drift is apparently the result of random noise on a CCD image. I thereby suspect that the nova and the nearby star was not convincingly resolved. The reported magnitude (likely a combined magnitude of the both objects) seems to suggest that the nova had not appreciably brightened by this time. Apr 29 image: the centroid of the mark seems to be slightly different from the May 4 one. Several nearby field stars were not sufficiently resolved. These finding suggest that the nova was not convincingly detected. Apr 5 image: the low resolution makes the distinction even more difficult. The rather constant reported magnitudes (likely a combined magnitude of the both objects) on all nights seem to suggest that the nova had not appreciably brightened by this time. My present conclusion is there was not convincing evidence of a long premaximum halt. I thereby strongly question the conclusion by Kimeswenger and Lechner (astro-ph/0309370). If there was not a long premaximum halt, the light curve of the nova was nothing unusual, which probably disqualifies the paper as an A&A letter -- this is no fault of Tabur, but premature conclusion by the authors on unverified data would rather be argued. I will communicate this information to the A&A office for potential help for their decision. Regards, Taichi Kato
