EFOSC2


 UT Target Type Setup Airmass Seeing Exp time Notes
 23: 28 SN2019cxt Follow-up
 gr13 slit1.0 1.3 " - Aborted - seeing too high
 23:33 SN2019gfm Follow-up gr13slit1.5 1.7 " - Aborted - seeing too high, object not found in acquisition
 23:37 AT2019mrk Classification gr13slit1.5 1.9 " -  Aborted - transient not seen in 75s acquisition 
 23:42 SN2019gbx Follow-up gr13slit1.5 1.5 1.9" 1800s Increased exposure time to compensate for shitty conditions.
 00:21 EG274 STD gr11+13+16 slit1.0+1.5 1.0 1.6"  
 00:45 AT2019mhb Classification gr13slit1.5 1.45 2.0" 1500s Not clear - best fits seem to be to a noisy SN-Ia ? Pre max, z~0.1
 01:22 AT2019mrn Classification gr13slit1.5 1.2 1.8" 1500s Maybe a SN-IIn, but maybe not? Spectrum is blue with narrow H-alpha but possibly still galaxy dominated- there's maybe some OII emission there too? 
 01:55 ZTF19abiagjr Classification gr13slit1.5 1.3 1.5" 1500s  AGN? Blue. Clear H-alpha, NII, H-beta at z~0.33. Possible broad feature at 4800A?

 2.0"
 2.0"
 2x2700s Used g13 and increased exposure time as conditions are poor
 04:13 AT2019lwu Follow-up gr11slit1.5 1.4 1.6" 1x2700s 
 05:10 EG131 STD gr11+13+16 slit1.0+1.5 1.2 2.2"  
 05:35 AT2019mwl Classification  1.05
 - Aborted  - target not seen in acquisition image
 05:42 AT2019mwa  Classification gr13slit1.5 1.15 1.5" 1500s Looks like a Ia-norm at z=0.13, but fits to Ia-pec 2006gz are intriguing.
 06:20 AT2019mtz Classification gr13slit1.5 2.0 1.5" 900s Clearly there in acquisition and 2D trace, but 1D resembles galaxy at z=0.04
Wiggle at 4200?
 06:40 SN2019jyw Follow-up gr13slit1.0 1.2 1.4" 1500s 
 07:10 AT2019mtw Classification gr13slit1.0 1.3 1.7" 600s AGN. Any sign of TDE or flare? Seems very blue now. Here's the 6df spectrum for reference http://www-wfau.roe.ac.uk/6dFGS/cgi-bin/show.cgi?release=dr3&targetname=g2025574-482226&tid=-1&specid=130495&ra=306.4890417&dec=-48.374

 08:59 AT2019mfv Classification gr13slit1.5 1.0 1.5" 900s Looks like a Ia-norm at z=0.085, around max
 09:21 SN2019esa Follow-up gr13slit1.5 2.1 2.4" 1x1500s Used g13 as conditions are poor and object at high airmass
 09:58 AT2019mpp Classification  gr13slit1.5 1.5 2.2" 900s Blue featureless continuum
