  FRB181228 was detected by the Molonglo Synthesis Radio Telescope (MOST) at a
position and time coincident with Transiting Exoplanet Survey Satellite (TESS)
observations, representing the first simultaneous multi-wavelength data
collection for a Fast Radio Burst (FRB). The large imaged field-of-view of TESS
allows a search over the uncertainty region produced by MOST. However, the TESS
pixel scale of 21" and the Full Frame Image (FFI) cadence of 30 minutes is not
optimal for the detection of an FOB with a possible millisecond duration. We
search the TESS FFIs and find no events with a limiting TESS magnitude of 16,
assuming a 30 minute event duration, corresponding to an optical flux density
upper limit of approximately 2000 Jy for a ~ms signal duration, assuming no
signal loss. In addition, the cosmic ray mitigation method for TESS
significantly reduces its sensitivity to short timescale transients, which we
quantify. We compare our results to the predictions of Yang, Zhang, and Wei
(2019) and find that the upper limit is a factor of two thousand higher than
the predicted maximum optical flux density. However, we find that if FRB181228
had occurred in the galaxy thought to host the nearest FRB detection to date
(37 Mpc), an FOB may have been detectable by TESS. In the near future, when
CHIME and ASKAP will detect hundreds to thousands of FRBs, TESS may be able to
detect FOBs from those rare bright and nearby FRBs within this large population
(if more sophisticated cosmic ray excision can be implemented).
