  Recently Jiang et al. reported the discovery of a possible short duration
transient, detected in a single image, spatially associated with a z~11 galaxy.
Jiang et al. and Kahn et al. suggested the transient originates from a
Gamma-Ray Burst (GRB), while Padmanabhan & Loeb argued the flash is consistent
with a supernova shock breakout event of a 300 M_sun population III star. Jiang
et al. argued against the possibility that this event originated from light
reflected off a satellite. Here we show that reflection of sunlight from a
high-orbit satellite or a piece of space debris is a valid and reasonable
explanation. As shown in recent works, the rate of point-like satellite
reflections, brighter than 11th magnitude, is >10 deg^{-2} day^-1 near the
equatorial plane. At higher declinations the rate is 5--50 times lower, but
still significant: about four orders of magnitudes higher than the rate
estimated for GRBs.
