M. Hurst, "The Astronomer", Basingstoke, England, communicates: "M. Collins, Everton, Bedfordshire, has reported his detection of a variable object in Aquila during photography with a 135-mm telephoto lens on Kodak 2415 film for the U.K. Nova/Supernova Patrol. The object was recorded on May 11.988 UT at mag 10.9. An image by Collins from 2000 Nov. 26.8 failed to show the object (limiting mag 12.8), which was also absent from a master patrol image obtained on 1997 Aug. 25.9 (limiting mag 13). A patrol image from 2001 Apr. 25.1 may show the object near mag 12.1, but as the Milky Way field is crowded this is rather uncertain. In response to an appeal, N. D.James, Chelmsford (0.30-m reflector), obtained a 30-s CCD frame of the field on May 16.966 UT and found the object at V = 12.6 (GSC system) in the measured position R.A. = 19h07m28s.41, Decl. = +11d44'45".8 (equinox 2000.0; 15 GSC stars, mean error 0".24 in R.A., 0".15 in Decl). The nearest star (R = 16.2) in the USNO A2.0 catalogue has position end figures 28s.34, 52".1." IAUC 7627 Mike Collins reports: I have checked through the first three (of five) volumes of the film archive and can so far report that on 57 epochs between 1989 March 25.1 and 1994 August 2.0 the suspect in Aquila was not visible, in some cases fainter than 12.8.
