Well we only have the historic outburst to go on, which wasn’t that well covered. However looking at the light curve it faded by a magnitude in just 5 days or so, and then two weeks to lose a further magnitude.
UGWZ type stars (if it is indeed one of these) can do wonderful things once they have faded – like re-outbursting a number of times after the primary outburst. They don’t do this every time though, just to keep us on our toes.
It’s going to be very frustrating due to it’s poorly placed position, but must remain hopeful that someone will get some good photometry and or spectroscopy during this outburst – but I’m not holding my breath.
