AAVSO Young Stellar Object (YSO) Section leader Michael Poxon (Great Plumstead, Norfolk, UK) requests coverage of the YSO V347 Aur beginning immediately.

He writes: "The T Tauri object V347 Aur is apparently having a major outburst. AAVSO observer John Pickett recorded a rise to 12.485 TG on 2021 Nov. 04.26806 UT from from its minimum of 15.445 TG on Oct. 27.28056 UT.

"The period [quoted in VSX] of just under a year may be a relic of the time when the star was thought to be a Mira. It is situated in a dark nebula and a faint 'cometary' arc is visible to one side. Observations in a wide variety of bands are encouraged." V347 Aur has a photographic range of 13.1 - 16.0:.

"A view of V347 Aur from 2MASS is below. The nebula is also visible on DSS colour plates in Aladin."

Coordinates (2000):  RA 04 56 57.04  Dec. +51 30 51.5  (from VSX entry for V347 Aur)
