PT Comae Berenices

[coatesg]

This was another HADS run taken on the 10th Apr - only really chance to do one star and then quickly reduce/plot. I'm going to struggle with suitable reference stars for this one - there's nothing really within a magnitude in the same field that I have (26'x18') - the nearest star in terms of magnitude in the east of the field below is saturated on some frames which is unhelpful - I may be able to trim those out before a submission. For timing purposes, this should be fine though. 

PT Com, HADS, Period 1.97hrs, Mag quotes as 12.03- 12.31, but my figures come out a little brighter using nearby stars in the APASS catalogue. A very straight rise for this star, almost like a sawtooth this profile. 

124 X 40sec, Johnson V filter, 350mm f4.53 newt, ST2000XM.
