TYC 1488-693-1 is an ~F2 type (T ~6750 K) eclipsing binary. It was observed in April and May 2015 at Dark Sky Observatory in North Carolina with the 0.81-m reflector of Appalachian State University. Six times of minimum light were determined from our present observations, which include two primary eclipses and four secondary eclipses. In addition,…

This paper continues the publication of the list of the new variables discovered at Astronomical Observatory, DSFTA, University of Siena, while observing asteroids for determining their rotational periods. Further observations of these new variables are strongly encouraged in order to better characterize these stars, especially those showing non-o…
