Abstract

We report high-cadence photometry of the ultra-fast ( $t_2\sim1.2$ d) nova V1674 Her during its rise to maximum light ( $V\sim6.3$ ) and the beginning of its subsequent decline. These observations from Evryscope and the Mount Laguna Observatory All-Sky Camera reveal a plateau in the pre-maximum light curve at $g\sim14$ ( $\sim$ 8 mag below peak) that lasted for at least three hours. Similar features (so-called pre-maximum halts) have been observed in some novae near maximum light, but to our knowledge the detection of a plateau in the light curve $\sim$ 8 mag below peak is unprecedented.
