Abstract:
We present new V, B-V and V, V-R color-magnitude diagrams for the
bulge globular cluster NGC 6388. These diagrams indicate that NGC 6388
is a metal-rich globular cluster with color-magnitude morphology
similar to that of 47 Tucanae. We have conducted a search for new
variable stars close to NGC 6388, finding three new RR Lyrae stars.
The membership of these and previously discovered RR Lyrae stars near
NGC 6388 is discussed. There is reason for believing that some of
these variables are nonmembers. Others, however, may belong to the
cluster and may be similar to the RR Lyrae star V9 in 47 Tuc.

Description:
Photometry is listed in table3 for 407 nonvariable stars in the field which
are more than 60 but less than 125 arcsec from the center of NGC 6388, and
which have formal uncertainties in each photometric index which are smaller
than 0.05 mag.
