Fermi ToO 100601-1-1

A ToO observation to observe PNV J11261220-6531086 at RA, Dec = 171.5632, -65.5231 (J2000) was approved at 2018-01-15 18:03:27 UTC.

The justification for the ToO is: A new Galactic nova, PNV J11261220-6531086, was discovered on January 14th at V~7.0 (although it probably brightened around January 3rd; CBAT Transient Object Follow-up Report), and has been spectroscopically confirmed as a nova. This object therefore satisfies the criterion we set in the approved Fermi Cycle 10 GI proposal #101290 (PI: Mukai), which aims to increase the number of novae detected as LAT transients, improve our phenomenological understanding of how gamma-ray properties of novae correlate with other multiwavelength data, and ultimately to understand the particle acceleration processes in novae. We therefore request a 1-week TOO. It is possible that it might brighten further to V~6, the criterion set in the proposal for a 2-week TOO.

The planned duration is 600.00 ks.

The autonomous request threshold during this ToO is LOW.

The ToO observation should begin between 2018-01-15 18:03:26 UTC and 2018-01-22 18:03:26 UTC.

The ToO observation was requested by DR. KOJI MUKAI.
