Active Dates: June 12, 2021 – June 14, 2021
Abstract:
Nova in Hercules: N Her 2021 = TCP J18573095+1653396 = ZTF19aasfsjq. Discovered by Seiji Ueda in Kushiro, Hokkaido, Japan, with a discovery magnitude of 8.4 on June 12, 2021.
Justification:
Please observe N Her 2021 as it continues to evolve, with observations of all types (visual, CCD, DSLR, PEP, spectroscopy) and multiple bands as instrumentation permits. Observations at a frequency of a minimum of one observation per night per band are recommended. For spectroscopy, 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, are recommended.
