862016-02-09 20:22:07hsiaoM. Stritzinger, E. Y. Hsiao, N. Morrell, M. M. Phillips, C. Contreras, S. Castellon, A. ClocchiattiNoneSN Ib1We report spectroscopic classification of AT 2016adj (cf. ATEL #8651) based on a visual-wavelength spectrum obtained on Feb. 9.2 UT with the 2.5-m du Pont Telescope (+ WFCCD) at LCO. The spectrum exhibits prevalent Na-I D absorption at the redshift of NGC 5128 characterized by an equivalent width of 0.44-nm. An additional feature coincident with the 578.0-nm diffuse interstellar band is measured to have an equivalent width of 0.06-nm, suggesting an A(V) value between 2 to 4 mag (Phillips et al. 2013, ApJ, 779, 38). Given the significant reddening the blue portion of the spectrum has very low signal-to-noise, however discernible features are present in the red portion of the spectrum that we attribute to H-alpha, the Ca-II near-infrared triplet, and Mg-II 922.7-nm. After manually de-reddening the spectrum assuming E(B-V)=1.0 and Rv=3.1 and then using the spectral identification tool superfit (Howell et al, 2005, ApJ, 634, 119), we find the spectrum of AT 2016adj to best resemble the Type-Ib supernova 1999dn around a week past maximum. This is in contrast to the Type II supernova classification previously reported (cf. ATEL #8655). Furthermore, close inspection of the spectrum reveals shallow absorption features at the expected wavelengths of He-I 667.8-nm and He-I 706.5-nm. Further observations are warranted to secure this classification. In addition, optical photometry was also computed from multiple images taken on Feb. 9.2 UT under photometric conditions with the 1-m Swope Telescope (+ e2v CCD camera) located at LCO. Computed photometry is as follows: filter u 18.943 +/- 0.040 filter B 17.395 +/- 0.041 filter g 16.565 +/- 0.038 filter V 15.701 +/- 0.031 filter r 14.613 +/- 0.021 filter i 13.304 +/- 0.017

Shappee (Carnegie), Subo Dong (KIAA-PKU)NoneSN II1The spectrum appears to be heavily reddened, which is consistent with the red photometric color measured in Atel #8654. We detect H-alpha emission line, and its classification is consistent with a Type II supernova. However, due to the relatively low SNR of the spectrum (taken at airmass ~2.9) and heavy reddening, we regard this classification as tentative in nature.

Cano (IAA, Granada)ePESSTOKilonova0.009841ePESSTO2017-10-16Classified in Ligo-Virgo GCN 21582 DATE: 17/08/19 01:46:26 GMT : The continuum is featureless, similar to the report of the first Magellan spectrum in Drout et al. (GCN 21547). But it peaks at 5500 and falls off rapidly in the blue. This is consistent with the Swift colours reported and the fading U-band and UV flux. The red part (beyond 5000Angs) can be fit with a black-body temperature of around 6000K or a power law. But neither are consistent with the turn over in the blue. There are no strong features in the blue that indicate line absorption or could be identified with known transitions. There are no Balmer lines, no Ca II H&K, or Si II absorption seen in supernova-like transients. We can certainly conclude this is not a young supernova of any type in this host, nor is it consistent with being a background supernova of any standard type. The UV dimming and maintaining of the red and NIR flux appears broadly consistent with many flavours of kilonova models.
