V618 Sgr bright outburst

Hi All

The Z And star, V618 Sgr is undergoing a bright outburst and is currently brighter than at any time since observations in the AID began in 1978.  This morning I made it mag 10.2.  It did start to brighten sometime in late 2017 to early 2018 and throughout 2018 remained around mag 11.6-11.8.  This is the first observation I've made since conjunction and it appears to have brightened further.

I'd encourage anyone to follow this interesting star.

Regards

Andrew
