Abstract:
We identify 51 blue horizontal branch (BHB) stars, 12 possible BHB
stars and 58 RR Lyrae stars in Anticentre fields. Their selection does
not depend on their kinematics. Light curves and ephemerides are given
for seven previously unknown RR Lyrae stars. All but four of the RR
Lyrae stars are of Oosterhoff type I.
