  We report results of VRI photometric monitoring of the T Tauri star plus disk
system HH30. We find that HH30 is highly variable over timescales of a few days
with Delta V~1.5 mag, Delta I~1.1 mag. Furthermore we find hints of periodicity
with periodograms indicating possible periods of 11.6 and 19.8 days. The VRI
photometry is available through the anonymous ftp service. We model the
variability with Monte Carlo radiation transfer simulations for a spotted star
plus disk system and find that the large variability is best reproduced with a
single hot spot and circumstellar grains that are larger than typical
interstellar grains. The apparent existence of a single hot spot and the need
for larger, more forward throwing grains is consistent with previous modeling
of HST imagery.
