Top panel: light curves of SN 2018aoq in various filters. Upper limits are indicated by downward pointing arrows. The letters “c” and “o” indicate the “cyan” (λ_eff ∼ 5330 Å) and “orange” (λ_eff ∼ 6790 Å) ATLAS filters, respectively. The non-detection (>18.85 mag) on 2018 March 28 (MJD = 58206) allows us to constrain the rise time to ≲5 d. Bottom panel: extinction-corrected V − I and R − I colour evolution for SN 2018aoq. The errors are the result of compounding errors in transforming from the V, r, and i filters to Johnson R and I. Open circles are extinction-corrected values taken from 8 well-sampled type IIP SNe (Table A.6). The black line indicates a fit to these data from which we infer E(B − V) = 0.04 for SN 2018aoq.
