(200 words excerpt, click title or image to see full post)

Following the posting on the Central Bureau's Transient Object Confirmation Page and on VSNET-Alert 13560 about a possible Nova in Lup we performed some follow-up of this object remotely through the 2.0-m f/10.0 Ritchey-Chretien + CCD of Faulkes Telescope South (MPC Code - E10).

Astronomers at Stony Brook University report on The Astronomer's Telegram 3536 that a spectrum of the possible Nova Lup has been obtained on 2011 Aug 9 at 00h19mUT. This was obtained with the SMARTS 1.5m RC spectrograph at Cerro Tololo and confirms that the eruptive object in Lupus is an Fe II nova near maximum. The spectrum (3700-5400A at 4.1 A resolution) shows the Balmer lines of hydrogen (H-beta through ...
