Absolute r-band magnitude light curve of SN 2020lao compared with several well-studied SNe Ic BL. These include the R/r-band light curves of GRB980425/SN 1998bw ($A_R^{\mathrm{MW}}=0.12$ mag, μ = 32.9 mag; Clocchiatti et al. 2011), XRF 060218/SN 2006aj (A_R^tot = 0.04 mag, μ = 35.7 mag; Ferrero et al. 2006), and SN 2020bvc (A_r^MW = 0.08 mag, μ = 35.4 mag), which also exhibited prominent early excess emission and high-energy signatures possibly produced from cocoon emission (Ho et al. 2020; Izzo et al. 2020). The ZTF r-band light curve of SN 2020ayz (A_r^MW = 0.03 mag, μ = 35.8 mag) is also included for comparison; like SN 2020lao, it was discovered shortly after explosion and lacks signatures of early excess emission (Ho et al. 2020).
