He adds the 2001 outburst was likely a short one and that the present brightness already surpasses the last event. Tonny Vanmunster, CBA Belgium Observatory has reported confirmation of the outburst on a CCD image: 2003 Sept 14.790, 14.0CR V475 SCUTI ( = NOVA SCUTI 2003 = POSSIBLE NOVA IN SCUTUM) Although initial reports suggested this object's spectrum (cf TA E- Circular 1912) was not displaying the typical characteristics of a classical nova, further reports are now available. On IAUC 8200, S. Siviero et.al., Asiago Observatory, write that the spectroscopic evolution as monitored with the Asiago 1.22-m and 1.82-m telescopes, allows them to classify the object as a normal nova. H. Yamaoka, Japan reports his precise astrometry of this nova, from CCD images taken on Aug 30.7UT by Berto Monard, South Africa, with respect to the UCAC-2 reference frame: RA 18h 49m 37.600s DEC -9 33'50.85" (2000). He adds that nothing is visible within 2" of this position on the red 1984 Digitized Sky Survey image or the 1999 2MASS public images. Werner Hasubick, Buchloe, Germany, reports that nothing was visible at the position of the nova on a photograph taken with a 280-mm f/2.8 lens on Aug. 23.9 UT (limiting mag 14). N. N. Samus, Institute of Astronomy, Moscow, advises that V475 Scuti has been assigned as the new designation for this object. Visual estimates: 2003 Aug 30.860UT, 9.2 (Gary Poyner, Birmingham); Aug 30.945UT, 9.6 (Rob Januszewski, 0.10-m Masutov-Cassegrain); Sept 1.915UT, 8.9 (Guy Hurst, Basingstoke, 15x80B); 3.922UT, 9.0 (Hurst); 4.926UT, 9.0 (Januszewski); 6.943UT, 9.0 (Januszewski); 13.874UT, 9.2 (Hurst); 14.83UT, 9.1 (Poyner, 0.22-m reflector) Charts and sequence for this nova were issued on CSN 118 and EWC 175 but the object is currently under-observed and further reports would be welcomed.
