  Here's a link to a crop of a widefield of the area reported to have been taken in the Netherlands on 20:22, 25 July UT, showing the nova.  Quite fuzzy and crowded and not terribly useful for a magnitude estimate, but it appears to lie between the 104 & 112 comp stars, quite bright.

  Thanks for the additional comp stars Mati.

    I have been taking time series images last night (V and I filters) and also saw a severe brightness increase. Had to cut down my exposure time by half.
    Will take some days to get the data analysed since I am put of town until Tuesday evening.

    I have also been keeping an eye on N Lup and noticed a steady rise and
    tonight brighter around 9.5.
