Had 90 mins of sky last night, and was able to see short term variations (minutes) of 0.5 mag. I don’t recall V404 Cyg doing this in 1989.  I certainly didn’t make any notes of short term variations. Pretty sure I would have recorded them.  Still can’t believe it’s been 26 years since I last ‘saw’ this beast (except on BRT images of course) 😉

It’s possible that these variations are caused by the jet as well as the disc and other phenomenon in the active area.  I’m pretty sure we’ll know a lot more once this outburst is over!
