VizieR Online Data Catalog: Type Ic SN 2020bvc UV to NIR LCs and opt. spectra (Ho+, 2020)

On 2020 February 4.34, SN2020bvc was detected at i=17.48+/-0.05mag at RAJ2000=14:33:57.01,DEJ2000=+40:14:37.5 as part of the Zwicky Transient Facility (ZTF) Uniform Depth Survey (ZUDS; D. A. Goldstein et al. 2020, in preparation) with the 48 inch Samuel Oschin Schmidt telescope at Palomar Observatory (P48).

SN 2020bvc was observed almost nightly in gri by the P48 for the first month postexplosion. We obtained additional ugriz and gri photometry using the IO:O on the Liverpool Telescope (LT) and the Spectral Energy Distribution Machine (SEDM) on the P60, respectively.

We obtained 10 observations of SN 2020bvc with the Ultraviolet/Optical Telescope (UVOT) and X-Ray Telescope (XRT) on board the Neil Gehrels Swift Observatory under a target-of-opportunity program (PI: Schulze). The first observation was on February 5.02 (Δt=1.35). We also obtained two 10ks observations with the Chandra X-ray Observatory under Director's Discretionary Time (PI: A. Ho), one epoch on February 16 (Δt=13.2) and one epoch on February 29 (Δt=25.4).

Two hours after the first detection, we obtained a spectrum using SEDM, a low-resolution spectrograph on the P60. On February 8.24, we obtained a spectrum using the Spectrograph for the Rapid Acquisition of Transients (SPRAT) on the LT.

We obtained 13 ground-based optical spectra using the SEDM, the Andalusia Faint Object Spectrograph and Camera (ALFOSC) on the Nordic Optical Telescope (NOT), the Double Beam Spectrograph (DBSP) on the 200 inch Hale telescope at Palomar Observatory, SPRAT on the LT, and the Low Resolution Imaging Spectrometer (LRIS) on the Keck I 10m telescope.
