Asas-sn calling for spectra of this object with a strange light curve. Quite southerly dec -65. I will try with sa100 as soon as its clear ( possibly tonight). Perhaps bernard or tom love can get it with lisa or uvex?

First clear night tonight, and I'm afraid I've got the new Lhires on the back, so probably not a goer. Could possibly have a look with the Alpy this weekend if it's clear.
