Dear Antonio, 

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,

Dear Michel,

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,

Increasing brightness

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.

Photometric reference stars in R, I?

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?

Rc and Ic magnitudes available

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

My first Nova

So this is my first Nova!

Canon 200 D, ISO400 + 10s 12s 15s 17s with the A200 / F900 mm Newtonian.

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:
