One of these objects was USNO-B1.0
0981-0723427, which was found to be in outburst on one of the near-infrared images from 1995, but faint on another nine images (Figure 1).
A search on VizieR (8) found entries for KP Cas in the USNOA2.0, USNO-B1.0 and GSC 2.3 catalogues with B, V, and R magnitudes in the range 17.6 to 18.8.
Astrometry of KP Cas on 10 images obtained under good conditions on JD 2454767 using Astrometrica (11) and the USNO-B1.0 catalogue gave a mean position for KP Cas of 0h 38m 54s.82 +61[degrees] 13' 0".5 [+ or -] 0".2 (J2000).
(3) N88A015933 (V= 19.08 [+ or -] 0.5) and USNO-B1.0 0968-0160072 (B= 19.60 and 19.44, R= 19.99) and suggested it might be a WZ Sge system because of the large outburst amplitude.
We measured the position of VSX 0747 on 8 images from January 24 at a time when it was near its brightest in the superhump cycle, using the Astrometrica astrometry software (19) and the USNO-B1.0 catalogue.
A search on Simbad (3) at the reported position reveals an object with identifiers GSC2.3 N152008120 and USNO-B1.0
