COMMISSION 27 OF THE I. A. U. INFORMATION BULLETIN ON VARIABLE STARS Number 2852 Konkoly Observatory Budapest 22 January 1986 HU ISSN 0374 - 0676 NOVA SCORPII 1985 On 24 Sept. 1985, Liller (1985), Vina del Mar, Chile, discovered a nova in Scorpius (17h53m19.4s ; -31deg49'09" (1950)). The object was of 10.5 mag. I started photographing parts of the Milky Way near Baade's windows in the constellations of Sco and Sgr, to find faint novae in outburst in July 1981. I worked with the GPO at La Silla (ESO). In July 1981 I photographed 20 fields on Kodak IIaO 160x160 mm plates. The field was 2deg x 2deg. In the same year I photographed the fields three times and treated the plates with a blink-comparator. In June 1982 Dr. Duerbeck from Muenster photographed a part of the fields, and then in August 1985 I observed once more. With the Optronics of ESO in Garching I found the pre-nova and could identify this object on some plates. The field No. 9 in my numeration with the coordinates of midpoint 17h53m and -31deg :(1985) shows the pre-nova near the center of the plate. I estimated the following magnitudes: Date Plate No. mag. of the pre-nova 23 July 1981 4853 GPO 16 7 Aug. 1981 4892 GPO 17 19 June 1982 5684 GPO (17 27 June 1982 5705 GPO (17 11 Aug. 1985 8649 GPO 16 17 Aug. 1985 8671 GPO 17.5 On the plate No. 456 of SRC (J) one can easily identify the pre-nova as a star of 17th mag. The identification chart of the nova is shown in Figure 1. I thank the ESO for using the instruments and stay at La Silla and Garching.
