Abstract
We present panchromatic observations and modeling of the Calcium-rich supernova (SN) 2019ehk in the starforming galaxy M100 (d≃16.2 Mpc) starting 10 hr after explosion and continuing for∼300 days. SN 2019ehk shows a double-peaked optical light curve peaking at tQ=Q3 and 15 days. The first peak is coincident with luminous, rapidly decaying Swift-XRTVdiscovered X-ray emission (Lx≃10 erg s- 41 -1at 3 days Lx∞t.3)
