\title{Nine new variables in the 66 Ophiuchi field}

\begintext

This paper continues the study begun in my previous publication
(Antipin, 1996). Nine more new variables were discovered in the
field $10\degr\times10\degr$ centered on 66 Oph (Var 34--42).
This study is based on Moscow collection plates taken with the 40 cm
astrograph in Crimea.

The data in Tables 1--4 contain information on the new variables.
Figures 1, 2 and the photometric standard are as in the previous paper.

This series of four studies was supported in part by the Russian
Foundation for Basic Research through grant No. 95-02-05189.
Thanks are due to Dr. N.N. Samus for his attention to this investigation,
to N.A. Gorynya and M.I. Antipina for their assistance during the
preparation of the figures, and to S.Yu. Shugarov for permission
to use his unpublished standard sequences.

Var 37. {\it Min II} 14.50.

Var 38. Red, fast enough, irregular variable.

Var 39. Red on Palomar prints.
The fragment of the light curve is given in Figure~3.

Var 42. Very unstable light curve. Maximum brightness varies.
The identification with IRAS catalog is uncertain. The
difference between coordinates from IRAS and those based on GSC stars
is about $16''$.
