Here are the raw astrometry of MisV0041 measured by the PIXY system
using USNO-A1.0 from four-night images taken by kenIchi Kadota.

17 59 48.94 -29 35 40.2  14.5mag
17 59 49.03 -29 35 39.7  14.4mag
17 59 48.86 -29 35 39.4  14.6mag
17 59 50.18 -29 35 41.1  12.6mag
17 59 50.10 -29 35 41.6  12.6mag
17 59 50.14 -29 35 41.3  12.5mag
17 59 48.96 -29 35 40.7  14.5mag
17 59 49.05 -29 35 39.8  14.4mag

The scatter of the position is large. But the position measured when
MisV0041 is bright well corresponds one another. So the true position
may be:

17 59 50.14 -29 35 41.3

In that case, the position is very similar to that of the 2MASS data.
I think I have to update the MisV list. Many thanks to Kato-san for
the research.

Best regards,
