The supernova SN 2020jfo was discovered by The Zwicky Transient Facility (ZTF; Bellm et al. 2019; Graham et al. 2019) in a weakly-barred spiral galaxy NGC 4303 (M61) on 6-th of May 2020. ZTF reported a rapidly rising young supernova in the nearby galaxy M61. Assuming the redshift of the host (M61, z=0.005224 from NED), and the distance of ~19 Mpc the SN was discovered around absolute ZTF r-band magnitude of Mr = -15.8. The follow up rapid spectroscopy reveals a blue continuum that suggests a core-collapse supernova origin and was classified as a young Type II supernova. Total amount of eight supernovae was discovered in NGC 4303 since the first one in 1926 followed by SN in 1961, 1964, 1999, 2006, 2008, 2014 and 2020.
