Hi,
is there anyone out there doing time series of this nova?
There are data on thee AAVSO site which are time series. Is any one from them here on the list?
I have data from Chile in V and I filter and it would be nice to combine time series from different places in the world to get a better hold on the peridocity which can be observed in the data. If I download the data from AAVSO it seems to be that R. Carstens (CROA) from New Zealand has submitted those time series.
It would be nice to get in touch with him.
Anyone knows his e-mail address?
Thank you for your help.
Regards,
Josch

Hi,
I had tonight another run on the Nova with CCD. In I filter the mean
magnitude is about 9.4 mag, about 0.2 mag lower than yesterday. In V filter
the mean magnitude is about 11.5 similar than yesterday.
There is some variation of the magnitude over time over a couple of hours of
observation.

Sky partly cleared late tonight (18 Aug) and I obtained a very poor quality
DSLR image (RGB). The nova appears to be a similar magnitude to 16 Aug
(~11.3, green channel, 12:15 UT). With my earlier three images, the nova
appeared roughly the same in R, G & B channels. Tonight however I notice
for the first time that the red channel appears considerably brighter than
the green, which is considerably brighter than the blue. Not much I can do
without a better image. Might clear a bit more later.

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.
