Proposal

Good morning, I'm Sauro Gaudenzi, my observer code is GSAD, in support of AAVSO alert nr: 896 I ask for the use of a telescope to observe the Nova N Wolf 2025 ( V462 Lup ), the applicant asks that observations be made with all filters, I ask for a weekly observation of 80 minutes divided as follows 20x60 seconds with filter B. 20x60 seconds with filter G, 20x60 seconds with R filter and 20x60 seconds with I filter, for at least one year to be started as soon as possible,

Abstract:

V462 Lup (N Lup 2025 = ASASSN-25cm = AT 2025nlr) was discovered by the ASAS-SN survey (K. Z. Stanek reporting for the ASAS-SN team) on 2025 June 12. 8700 UT, magnitude 8.7 Sloan g. SPECTROSCOPY by Y. Tampo (SAAO) using the SAAO 1-m Lesedi telescope on 2025 June 14.745 UT shows a classical nova (ATel #17228, https://www.astronomerstelegram.org/?read=17228). COORDINATES (J 2000): RA 15 08 03.27 Dec. -40 08 29.6. PROGENITOR: S. Otero (AAVSO) reports the approximate minimum of the nova is 22.3: B, obtained from a MAMA srcj plate. PHOTOMETRY: see Justification. View the light curve via the AAVSO Light Curve Generator (https://www.aavso.org/LCGv2/).

Justification:

The AAVSO requests coverage of this nova with observations of all types (visual, CCD/CMOS, DSLR, PEP, spectroscopy) and in all filters as it evolves. All novae are worthy of as good coverage as possible for as long as possible to support research on novae being carried out now and in the future. Spectroscopy is also encouraged where possible. See sections below for cadence and other observing recommendations. NOTE: E. Kazarovets (Inst. of Astronomy, Moscow) reports assignment of the GCVS name V462 Lup (via CBET 5570, D. W. E. Green, Ed.). PHOTOMETRY (selected from observations submitted to the AAVSO): 2025 Jun. 4.678 UT, <4.7 unfiltered (R. H.
