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)
