Spectroscopy and multiband photometry are required.
Clear skies,

Dear Antonio,
I am an AAVSO member from India. Could you please share me observed image of target and images of comparison stars?
With regards,
Pradip Karmakar
Hi Pradip
I used the chart X25766H from AAVSO Variable Star Plotter. The comparision stars (96;102) are in NW direction.

Cheers
Dear Antonio,
Thanks for this link. From this image , I hope the target and the two corresponding comparison stars are situated in the Northern Hemisphere. Is it right? Maybe I am wrong.
With regards,
Pradip Karmakar
Indeed, in the Perseus constellation, my visual estimation 4h52 UTC give +9.9
Here a sketch of the field

Dear Michel,
Thanks for sharing me the sketch of the nova and comparisonstars (96 and 102). In the light curve we have five points and three bigger spots. What does it mean by these bigger spots? To measure the magnitudes of the targeted nova, can we use differential photometry technique?
With regards,
Pradip Karmakar
Thank you Pradip
The bigger spots are the photometric estimations the small points are the visual ones

Hi all,
with our observatory - WBRO (K49) - me and Massimo Banfi are observing the N Per 2020 right now. In last 2,5 hours the star has increased his brightness of 0.3mag (in V and R filters) reaching the maximum in R at 7.6. Keep obseving.
Thanks for all the information on this event. The VSP provides a nice chart and table of photometry in the B and V passbands. Is there a plan to provide photometry for the reference stars in R and I in the near future?
Hey Michael,
those magnitudes are available, but for them to be shown you need to check the corresponding boxes at the bottom of the VSP chart form.
Check Rc and Ic and then the photometry table will show magnitudes in those passbands too.
Cheers,
Sebastian

So this is my first Nova!

Playing with the comprison stars was crucial. 000-BNS-430+434+431 at 2459184.25 came close to the NOVA. And is close to other V band obs. With these results:
