|The variability of GSC 2563-00494 was discovered by ROTSE-I (Akerlof et al., 2000).
The variable was classified as a DSCT star with the period 0.187155 days. Later
was observed by Jin et al. (2004) who attributed it to eclipsing variables, with
a doubled period (0.374370 days). But the phased light curve of the star in
al. (2004) shows that the period is wrong. The true period must be longer.
I reinvestigated the star using the same ROTSE-I data. I confirm the eclipsing nature of this variable, but the period is twice the 1-day alias to that originally found by ROTSE.
