Summertime targets from Rich Townsend (June 2009)
Ap/Bp stars - chemically peculiar with strong magnetic fields
CU Vir (HD 124224) -- short period, quite bright, the best-known 'stellar pulsar' (main sequence star with ~0.5d pulsed radio emission).

B = 4.89
V = 5.01
A0Vp
V 2052 Oph (163472), which is a combination beta Cep/He-strong B2 star with a 3.64d period. Again, quite bright.

B = 5.883
V = 5.834
B2IV-V
V 1671 Cyg (HD 184927), which is a bit dimmer, and has a longer period, but appears to have a very oblique, strong field (seen from near pole on).
