Caption: Figure 1.

Panel (1): the unfolded light curve of 2017 QJ216 in Rubin First Alerts. Super-fast rotation is visually identifiable with variability (∼0.1 mag) substantially greater than the typical photometric precision (∼0.03 mag). Panel (2): the folded light curve of 2017 QJ216 over its two-peaked solution. Panel (3): the periodogram power as a function of frequency, showing the 20.3 minute period as the preferred two-peaked solution.
