There is a lot more UBV data for field stars near the LMC nova, but it
usually involves digging through old papers. A compiled sequence of stars is
presented below, but has been done in a hurry, so excuse me if references
are not so complete.
LMC Nova 2000. Sequence.
====================
Name HDE V B-V RA (2000) DEC.
======================================
269451 12.56 -0.05 5:22:20.3 -70:36:06
269510 11.11 +0.22 5:25:08.2 -69:53:44
269584 10.83 +0.52 5:27:31.6 -70:26:27
NS-70o91 12.78 -0.23 5:27:33.8 -70:36:48
NS-70 93 269585 12.84 +0.07 5:27:48.7 -70:07:27
NS-70 94 13.13: -0.14 5:28:57.9 -70:20:29
These are LMC B or A type supergiants, and the same data is (or should be)
in the Geneva Catalogue of Photometric Data.
Other useful BV data comes from the work on foreground stars by Gochermann,
Grothues et al, as follows.
FD 989 269505 10.92 +0.43 5:24:56.2 -70:16:11 GSC 9166.178
FD 1000 269520 10.24 +0.97 5:25:26.1 -70:11:35
11.67 +0.56 5:25:45.3 -70:05:44 GSC
9166.556
11.84 +0.62 5:26:52.1 -70:12:55 GSC
9166.30
Sorry, no time to find all other aliases for the ids NS = N. Sanduleak.

This particularly region of the LMC is especially prolific for novae. Within
a 1degree radius of the
new nova, other novae have appeared in 1948, 1970 (2 novae), 1981, 1987 and
1988, that I know of.
I haven't got a complete census at the present moment.
