Q1991/100 I noticed that the Collins variable Q1991/100 is identified with a G-type star with significant IR excess (IRAS source) and a likely ROSAT identification. This star probably needs further detailed study. The star is not very bright in 2MASS. ## Q1991/100 GSC2390.1549 051621.37 +304234.8 (2000.0) 8.88 1 N USNO1200.03103888 051621.334 +304235.00 (2000.0) 9.4 10.5 2MASS 051621.243 +304232.49 (2000.0) 8.933 8.217 8.199 IRAS05131+3039 051309.8 +303924 (1950.0) F12=12.02 F25=4.78 F60=0.76 F100=1.90L VAR=38 LRS=15 blue featureless, spec.index=2.5 II: variable star with 'young' O-rich circumstellar shell 051621.3 +304234 (2000.0) Q1991/100 8.5 10.5 051620.5 +304233 (2000.0) 1RXS-F_J051620.6+304234 0.024 0.10 1.00 051622.3 +304240 (2000.0) IRAS05131+3039 11.860 4.871 0.770 1.849L 38% 2(LRS) 051622.3 +304240 (2000.0) SSC05131+3039 11.860 4.871 0.770 1.849L 051621.2 +304232 (2000.0) 1072 0.53 TYC2390.1549.1 plx=32.8(35.8) (0.13 0.15) 051621.1 +304231 (2000.0) 1048 0.71 TYC2-2390.1549.1 (10.55 0.06) (11.38 0.08) 051624.8 +304146 (2000.0) HD242063 10.8 G0
