Nothing appears at this position on the CCD Atlas of Deep Sky Objects (Buil and Thouvenot 1991, Sky Publ.), though there is a foreground star of mag about 16 located about 10" west and 25" south of the galaxy's centre. P. Garnavich, P. Challis, and R. Kirshner, Center for Astrophysics, report that an image taken by R. Jansen at the 1.2-m telescope on Mt. Hopkins on Apr. 7.2 clearly shows a new star (Johnson R magnitude 16.4 +/- 0.1) at the position reported by Johnson; no object appears on the Palomar sky survey prints at that position. IAUC 6157 NOVA AQUILAE 1995 Brian Skiff, USA advises us that C.G.Mason et al at the University of Minnesota have obtained infrared photometry suggesting recent dust formation in this nova. There is the possibility of a DQ-Her type decline followed by a recovery as in the case of V705 Cas. Observers are strongly urged to monitor this nova closely and those with CCD equipment may be able to follow it down to a deep minimum should this occur. NSV 06481 K.Takamizawa, Nagano, Japan reports his photographic discovery of a brightening of NSV 06481 (0.10-m OG and T-Max 400 film): 1994 May 6.595UT, 14.1pg; 1995 Mar 28.660, 12.4pg M.Iida reports that the object is listed in the NSV as having a range of 14.5-[15.5p but with unknown type. He adds the following information from atlases: Vehrenberg [15.4; Lick 14.5; GSC 14.9. He suspects this may be some form of eruptive variable. M.Iida has subsequently reported further observations with 0.16-m +ST6 (CCD) unfiltered: Apr 1.472, 11.2; 1.550, 11.0; 4.569, 10.5. The position from the GSC is: 13h 53m 32s.74 -29o 05' 42".0 (J2000.0) V1413 AQUILAE Giovanni Sostero, Italy reports that photoelectric photometry of the symbiotic nova V1413 Aquilae on 1995 Mar 12.145UT yielded V=11.2, B-V=+1.0. It is believed this star is undergoing an outburst phase. John Bortle, USA independently reports a brightening: 1994 Dec 29.96< 13.0; 1995 Feb 13.45, 12.0; Mar 29.40, 11.2 AL COM Further observations: Apr 5.830, 11.8 (J.Pietz, Germany); 6.902, 12.3 (Guy Hurst, Basingstoke, UK); 6.927, 12.6 (Gary Poyner, Birmingham UK); 6.996, 12.7 (Poyner); 7.006, 12.7 (Poyner); 7.936, 12.6 (Hurst) Guy M Hurst
