ASAS-SN request AT2018oh

Postby Robin Leadbeater » Sun Feb 04, 2018 8:11 pm

I have had a request for a spectrum of possible supernova AT2018oh/ASAS-SN18bt discovered today (mag 15)

I am clouded out again tonight but perhaps someone else might like to try.
Below is the email request

Cheers
Robin

Dear Robin,

ASAS-SN has just discovered ASASSN-18bt (2018oh on TNS). It is in the Kepler's K2 field so could be of great interest with high-cadence Kepler observations. Could you please take a spectrum if possible?

Best,
Subo

I managed to get 10 mins on it in a break in the clouds. It is a type Ia.

(spectrum and typical SNID fit below)
It could reach ~mag 14 in the next few days.

Cheers
