Comments

SNID fits are not great

NIR observations aborted

SN was not immediately obvious so we moved on, especially with increasing airmass

Blue continum with a few narrrow absorption feartures. No SNID match

SNID provides a range of options

Doubled exposure to combat clouds

Doubled exposure to combat clouds, includes focus check

Blue continum, no SNID match

No SNID match

SNID suggests Ic at low redshift

Slight overlap with twilight - 3 minutes
