According to AAVSO Alert Notice no. 447 the second Nova in Scorpius this year was discovered by John Seach from Chatsworth Island in Australia and independently by Yuji Nakamura from Kameyama in Japan on 6^th of September 2011 like a 9.8 - 9.7 mag star, with coordinates: α: 16^h36^m43^s, δ: -41° 32′ 33″. Spectroscopic observations suggest, that this is a classical Fe II-type nova.

We checked our observations' archive in San Pedro de Atacama, Chile. Unfortunately in the day of discovery our cameras were turned off, but we have a picture taken a day earlier, and in this picture the nova is not seen. In a picture taken on September 7^th the nova has brightness nearly 9.8 magnitudo.
