Asas-sn supernova survey has picked up an object with rapid and odd variability and is urgently seeking spectroscopic observations.
If you have a spectrograph, even a humble star analyser, take a spectrum. Don't forget to also take a reference spectrum, preferably a B or A type star with a high quality reference spectrum. I will repost later today with a few good suggested references, maybe ken can also suggest.
