Proposal #645

Hello, I'm Sauro Gaudenzi, my observer code is GSAD, in support of AAVSO alert nr 906, I ask for the use of a telescope to observe the subject V1935 Cen (N Cen 2025 = PNV J14372177-5847400), I ask that a weekly observation of 60 shots of 60 seconds each with V filter and an observation of 60 shots of 60 seconds each with B filter be made because these 2 filters are sensitive to temperatures and metals, I ask that observations begin immediately until 30 September 2027:
Abstract:

V1935 Cen (N Cen 2025 = PNV J14372177-5847400) was discovered by John Seach (Grafton, NSW, Australia) at unfiltered magnitude 6.2 on DSLR images obtained on 2025 Sep. 22.396 UT (via CBET 5611, ed. D. W. E. Green). SPECTROSCOPY: Low-resolution spectroscopy by R. Kaufman (Bright, Victoria, Australia) obtained on 2025 Sep. 23.383 UT indicates the object to be a classical nova (via CBET 5611). COORDINATES (J 2000): RA 14 37 21.80 Dec. -58 47 40.8 (VSX). NEARBY STARS: A. Pearce reports Gaia DR3 5879255150965919104 (G magnitude 16.7), located within 0.35". E. Guido, M. Rocchetto, and L. Izzo report Gaia DR3 5879255150966541696 (G-band magnitude 20.85), located approximately 1.302" away (via CBET 5611). PHOTOMETRY: see Justification. LIGHT CURVE: View the light curve via the AAVSO Light Curve Generator (https://www.aavso.org/LCGv2/). IMAGES: Animation by Guido et al. (via CBET 5611) comparing their image taken Sep. 22.55 UT and a 1993 POSS plate posted at URL https://tinyurl.com/PNCEN202
Justification:

The AAVSO requests coverage of this nova with observations of all types (visual, CCD/CMOS, DSLR, 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. NOTES: The name PNV J14372177-5847400 was assigned when Seach's discovery report was submitted to the IAU CBAT TOCP. E. Kazarovets (Inst. of Astronomy, Moscow) reports assignment of the GCVS name V1935 Cen (via CBET 5611). PHOTOMETRY (selected from observations submitted to the AAVSO): 2025 Sep. 21.366 UT, <11.0 unfiltered DSLR (Seach); 22.55, 5.8 unfiltered CMOS (E. Guido, M. Rocchetto, and L. Izzo, remotely from near Moorook, Australia, via CBET 5611); 22.9125, 6.4 (A. Amorim, Florianopolis, Brazil); 23.4688, 7.0 (N. Brown, Yanchep, W. Australia); 23.4885, 6.970 TG (A. Pearce, Nedlands, Western Australia); 23.4885, 7.276 TB (Pearce); 23.4956, 7.416 B +/-0.001 (Pearce); 23.4959, 7.197 V +/-0.001 (Pearce); 23.496, 6.8 (Pearce); 23.4961, 6.159 R +/-0.001 (Pearce); 23.4963, 5.354 I +/-0.001 (Pearce); 23.9200, 7.5 (J. Aguiar da Silva, Campinas, Brazil); 23.9521, 7.5 (Amorim); 25.4729, 7.4 (Pearce); 25.4756, 7.7 (Brown); 24.7278, 7.5 CV DSLR (S. O'Meara, Maun, Botswana).
Waiting for your response, I wish you all a good day
