It's had around 11 official ascents, mostly from the SW. Maybe another one or two unofficial?

Dodo Kopold soloed a new line on it last year - it's in the 2010 AAJ - and there was a hard Russian route on it in the mid-90s.
It's also known as Annapurna Dakshin, so search for that too. It's a good looking mountain.
