John Greaves:
The data can be found on TASS CD 23 in collected.big as number 58999 It is GSC 0175 2509. SIMBAD reports nothing, can't find any catalogue match in a swathe of cats. This star is a short period pulsating variable of 0.1448 day period (3.62 h). Magnitude ranges are 10.85 - 11.25 V and 10.35 to 10.75 I. It has a symmetrical and quite clean phased light curve so from that and the period I'm assuming it is a delta Scutid variable, dSct. Tycho data _suggests_ a (B-V)J of about 0.5 I've made a GIF but I've nowhere to put it, and I assume the list will block attachments. I think there are enough data points on this one to warrant an IBVS as is. Who wants to do it, coz I don't! Anyone check the possible variability type please. Can send raw data to list as an email if needs be.

I asked Chris Lloyd to independently check the data for this one and he came up with a couple of slightly shorter possible periods, as well as noting that an EW solution of roughly twice the period was also possible.
