  We attempt to a detect signal of Yarkovsky-related acceleration in the orbits
of 134 main belt asteroids (MBAs) we observed with the University of Hawai'i 88
inch telescope, supplemented with observations publicly available from the
Minor Planet Center and Gaia Data Release 3. We estimated expected Yarkovsky
acceleration values based on parameters derived through thermophysical
modeling, but we were not able to find any reliable detections of Yarkovsky in
our sample. Through tests with synthetic observations however, we estimated the
minimum observational arc length needed to detect the Yarkovsky effect for all
of our sample MBAs, which in nearly every case exceeded the current arc length
of the existing observations. We find that the Yarkovsky effect could be
detectable within a couple of decades of discovery for a 100 m MBA assuming
0.1" astrometric accuracy, which is at the size range detectable by the
upcoming Vera Rubin Observatory Legacy Survey of Space and Time.
