New Observations of AD Serpentis.

RAYMOND S., MORALES X. and OSBORN W.

Abstract (from CDS):

The little-studied star AD Ser has been investigated utilizing archival data as well as new CCD observations. AD Ser is found to be a semiregular variable with a V range of about 1.5 mag and a persistent, but likely somewhat variable, period of 90 d.
