We observed the bright, young, and nearby Type Ia ASASSN-21kl/SN2021pit (Stanek et al. 2021; Cartier et al. 2021) in NGC 1448 (D = 18 Mpc, Riess et al. 2016; which also hosted the Type Ia SN2001el and the Type II SN2003hn) with the MAS500 Officina Stellare RC 50-cm telescope + FLI CCD camera at El Sauce Observatory, Chile, on 2021 June 11.425 and June 14.428. These observations were obtained as part of the Observatorio Mancomunado de Astrofisica (OMA), a collaboration of four Chilean universities (UDP, PUCV, UFSM, UAI) and the Millenium Institute of Astrophysics (MAS) with access to small aperture telescopes in the El Sauce Observatory near Ovalle. The supernova is clearly detected in BVri bands at RA = 03:44:30.20, DEC = -44:37:57.3 (J2000.0), with astrometry obtained using astrometry.net (Lang et al. 2010). Using APASS DR10 photometric measurements of stars in the field, we report the following preliminary magnitudes of the source: B=14.10 +/- 0.10 mag, V=13.00 +/- 0.04 mag, r=12.67 +/- 0.03 mag, i=13.44 +/- 0.04 mag (June 11.425) and B=13.90 +/- 0.10 mag, V=12.62 +/- 0.04 mag, r=12.27 +/- 0.04 mag, i=13.10 +/- 0.04 (June 14.428). More observations are planned.
