  We present highly sampled photometry of the supernova (SN) 2023ixf, a Type II
SN in M101, beginning 2 days before its first known detection. To gather these
data, we enlisted the global Unistellar Network of citizen scientists. These
252 observations from 115 telescopes show the SN's rising brightness associated
with shock emergence followed by gradual decay. We measure a peak $M_{V}$ =
-18.18 $\pm$ 0.09 mag at 2023-05-25 21:37 UTC in agreement with previously
published analyses.
