sn2016fnr

[Robin Leadbeater]

Unfortunately I was clouded out in the days following the discovery by UK supernova hunter Ron Arbour of sn2016fnr on 29th August

https://wis-tns.weizmann.ac.il/object/2016fnr

and the type (Ia) had already been confirmed before I was able to take a spectrum last night.

My spectrum taken at ~ mag 16 using the modified ALPY "200" however confirms with high confidence the classification of a type Ia supernova near maximum light as assessed using the supernova identification program SNID which is a fortran program used by the professionals, running on my newly installed Linux (Ubuntu) laptop

The attached shows my spectrum (black) overlaid on the best fit spectrum from the SNID library

SNID seems to be more sophisticated and is doing a better job than the on line GELATO program I was using before so the steep learning curve of struggling with linux and fortran compilers (the lat time I did something like this was over 30 years ago!) seems to have been worth it

Cheers
