VizieR Online Data Catalog: UV and optical spectra of type IIP SN2021yja (Vasylyev+, 2022)

The SN 2021yja was observed as an HST disruptive target of opportunity on 2021 September 16 (+9d after explosion), 2021 September 21 (+14d), and 2021 September 28 (+21d) using the CCD (52"x52" field of view) detector of the Space Telescope Imaging Spectrograph (STIS). See Section 2.1.

Optical spectra of SN 2021yja were obtained using the Kast Double Spectrograph on the Shane 3m telescope at Lick Observatory. The spectral sequence consists of 10 epochs and spans +4 to +121 days. All observations cover a wavelength range from 3632 to 10754Å. See Section 2.2.

Follow-up photometry of SN 2021yja was performed with images from the 0.76m Katzman Automatic Imaging Telescope (KAIT) as part of the Lick Observatory Supernova Search, as well as with images from the 1m Nickel telescope at Lick Observatory.

The SN 2021yja was observed photometrically and spectroscopically in the UV with the Neil Gehrels Swift Observatory. See Section 2.3.
