Nova in Sagittarius: N Sgr 2021 No. 2
Active Dates: April 4, 2021 – None
Abstract:
None provided.
Justification:
Please observe N Sgr 2021 No. 2 as it continues to evolve, with observations of all types (visual, CCD, DSLR, PEP, spectroscopy) and multiple bands as instrumentation permits. Dr. Fred Walter (Stony Brook University) recommends observations every few hours in the early stages as the nova continues to brighten. Frequency of observation once past peak depends on the rate of decline, but should be a minimum of one observation per night per band. For spectroscopy, he recommends spectra in blue to observe He II 4686, H-beta, and the Bowen blend (4640A), in addition to H-alpha, with a cadence of one spectrum per clear night.
