[vsnet-alert 7012] Sequence for IM Nor



Should the recurrence of IM Nor be confirmed, there is a very handy
photoelectric sequence by Loden, only 5' SE of the nova. It is field 2313
in Astron. Astrophys. Suppl. 41,173 (1980). I have given each star its GSC
number, and reproduced Loden's data.

Note 1.  While  Tycho1 gives V = 11.44, Tycho2 gives V =12.133, B-V = 0.506.
All other V mags are consistent with Tycho data or GSC mags.
