Spectral observations of stars associated with nebulae, PP52, PP57,
PP63, and PP89, are reported. The star PP52 is of spectral type A and is
associated with a reflecting nebula. PP57 is a nonstationary star. A
weak object (1079-0122733) immediately adjacent to PP57 is highly
variable. It is shown that the nebulae PP63 and PP89 are cometary.
