Andrew Howell, Curtis McCully, Estefania Padilla Gonzalez, Craig PellegrinoGlobal SN ProjectSN Ia0.078525Global SN ProjectWe find best fits to SNe Ia around maximum light. The supernova is closest to WISEA J094808.37+064910.2 (z = 0.078525, 2004SDSS3.C...0000:; value from NED). This redshift is consistent with narrow host galaxy lines present in the spectrum. Although the spectrum is low S/N, as it was taken near the faint limit of the instrument and the object was 32 degrees from a 98% full moon, we identify the Si II 6355 feature and measure a velocity of approximately 10,000 km/s. Adopting the distance modulus computed from this redshift (37.7), the r-band absolute magnitude of the object roughly coeval with the spectrum is -19.1 (apparent magnitude 18.6, from ZTF). This absolute magnitude and velocity is consistent with a SN Ia near maximum light.2020TNSCR3963....1B
