  We search for signs of falling evaporating bodies (FEBs, also known as
exocomets) in photometric time series obtained for $\beta$ Pictoris after
fitting and removing its $\delta$ Scuti type pulsation frequencies. Using
photometric data obtained by the TESS satellite we determine the pulsational
properties of the exoplanet host star $\beta$ Pictoris through frequency
analysis. We then prewhiten the 54 identified $\delta$ Scuti p-modes and
investigate the residual photometric time series for the presence of FEBs. We
identify three distinct dipping events in the light curve of $\beta$ Pictoris
over a 105-day period. These dips have depths from 0.5 to 2 millimagnitudes and
durations of up to 2 days for the largest dip. These dips are asymmetric in
nature and are consistent with a model of an evaporating comet with an extended
tail crossing the disk of the star. We present the first broadband detections
of exocomets crossing the disk of $\beta$ Pictoris, consistent with the
predictions made 20 years earlier by Lecavelier Des Etangs et al. (1999). No
periodic transits are seen in this time series. These observations confirm the
spectroscopic detection of exocomets in Calcium H and K lines that have been
seen in high resolution spectroscopy.
