                      On The Position of FG Ser


As part of a program conducted to improve the position of southern variable and
suspected variable stars (Lopez and Girard 1990), the case of FG Ser is herein
presented.

The GCVS IV gives the position of this variable to the nearest minute of arc in
Dec, which implies that the coordinates are only approximate.

We have identified FG Ser in a Kodak blue plate taken on August 17,1990 with
the Yale Southern Observatory double astrograph.  A set of 11 AGK3 stars was
used as reference system; the least-squares adjustment gave a standard error of
0.38" in both RA and Dec.

The new position we have obtained for FG Ser (equinox B 1950.0) is:

alpha =18h 12m 32.90s   delta = -0d 19'52.9"

(the difference between our new position and the one quoted in the GCVS -in the
sense new position minus GCVS- is 0.048m in RA and -2.882' in Dec).

This new position of FG Ser is in excellent agreement with Allen's (1984)
coordinates of the symbiotic star AS 296.  This allows to conclude that
Schweitzer's (1990) identification of FG Ser with AS 296 is correct, at least
from the positional point of view.
