HI all,
we finally have the Central Bureau Electronic Telegram announcement today for this supernova discovery which is now designated as SN2012dn.
Congratulations once again Stu.
And, as mentioned above, the CBET says that this object was imaged by the 8-m Gemini South telescope and shows it to be a type-Ia supernova
approximately a week before maximum light and suggests that 2012dn is a super-Chandra event.
