Abstract:
The amateur observer Lennart Dahlmark has published a useful series of
IBVS notes listing a number of candidate variable stars, most of which
were new. Although adequate charts and reliable semi-accurate
positions were supplied, no other identifications were usually given.
If the stars are to be recovered for further study and linkage within
other surveys (IRAS, etc.), then precise positions must be determined
to make identification unambiguous within crowded galactic fields.
