    Now that's super cool! The AAVSO give these coordinates for V404 CYG: 20 24 03.83 +33 52 02.2 (J2000.0)

    Here's the ESA press release when the outburst occurred last June and the chatter on AAVSO at the time.

    It looks like it had another huge outburst again a few days ago, according to recent observations on AAVSO

    Thanks for the AAVSO chatter link Steve - the second to last post, made today, includes a link showing a video of the huge brightness changes over only 5 hours: http://spiff.rit.edu/richmond/ritobs...04cyg_anim.gif
