1200s Gr#13 spectrum (at request of Kate - to check if really is a young Ia)

02:10 SN 2013hx

Nothing in first acquisition image (checked with PESSTOEFOSCPHOT). Took 200s acquisition image, very faint source at expected position, but too faint to acquire. Switched to R#642 filter and took new 200s acquisition. Could now acquire target, started 2700s exposure in case there is some strong line emission - but given how faint this guy was to acquire, I really do not expect to see anything.

We do not see a trace in the spectrum - hence we are abandoning the remaining spectrum.

Reduced spectrum and extracted at expected positon of target, continuum is at 0 flux. However, we see a broad (7000 km/s) Halpha line at z=0.13.
