SN 2022fuc is a young SN II discovered and made public by Giancarlo Cortini (Monte Maggiore Observatory-Predappio-ITALY; TNS Astronomical Transient Report No. 143059).
The SN was detected by the Zwicky Transient Facility (ZTF; Bellm et al. 2019; Graham et al. 2019) about 9 hours prior on 10:31 UTC. Followup observations were rapidly triggered by ZTF (following the methodology of Gal-Yam et al. 2011) as well as by the Precision Observations of Infant Supernova Explosions (POISE; ATEL #14441) collaboration. we obtained spectra using the SEDM spectrograph mounted on the robotic 60`` telescope (P60) at Palomar Observatory, the KAST spectrograph on the 3-m telescope at Lick Observatory and the Gemini Multi-Object Spectrographs (GMOS) mounted on the Gemini North telescope ar Mauna Kea Observatory. Our first SEDM spectrum is largely blue and featureless, with a possible bump around ~4600Å similar to that observed for the Type II SN 2021yja, consistent with the classification reported by Kawabata & Taguchi (TNS Classification Report No. 12198). Swift follow-up is underway and additional follow-up is encouraged.
