[vsnet-alert 24539] v1223 sgr since 2002

Sat Aug 15 17:54:10 JST 2020

Hi,

just to get an idea and appreciation for the recent behaviour of V1223 Sgr,
have a look at the attached file.
It tables nightly averages derived from timeseries photometry against the
observations mid-times.

Nightly fluctuations of V1223 Sgr vary from 0.1 to 0.3mag on most nights,
but during active states they reach well over 1mag, as recently observed.
During such periods and actually always, snapshot photometry will render
different results from those tabled here.
