Quite a productive period at the moment third night on the trot! Another two HADS stars: 

V488 Gem and GSC 4935-0348 (ASAS J115229-0245.1). The latter looks quite symmetric for a HADS star - usually a much quicker rise than this.

V488 Gem is in quite a busy field:

Good work Graeme. Any idea why the second one is more noisy even though it is brighter?

Declination of -2 so higher airmass, and our row of terrace houses forms an artificial horizon due south of my dome! Heat from the houses, central heating, open fires... not great !! (Also, the scales are different on the graphs - the second one only seemed to vary by <0.2mag)
