Report on behalf of the University of Wyoming GRB response team and the
FUN GRB collaboration:

We observed the optical afterglow of GRB 030329, identified in Torii (GCN
1986), in the Johnson V filter with the RBO 0.6m telescope at Red Buttes
Wyoming. We obtained 25, 300s exposures. Observations were undertaken
between 02:26UT and 6:00UT, on March 31st. The observations were carried
out under fair seeing conditions. Aperture photometry was performed and
calibrated utilizing the standards reported by Henden et al., (GCN 2023).
We initially measured the magnitude of the OT to be V=16.71, which faded
by 0.15 mag during our observational period; however, there appeared to be
a brightening. Errors were on average +/- 0.018.

Further aperture photometry is being performed and observations are
planned.

J. Schaefer, D. Gibbs, M. Nysewander, R. Canterna, and D. Reichart report
on behalf of the FUN GRB collaboration:

We imaged the entire 314 sq arcmin error box of the IPN burst, GRB 030413
(Hurley et al. GCN 2135) with the UWYO 0.6m Red Buttes Observatory (RBO)
Telescope beginning 21.701 hours after the burst (April 14.2199 UT). We
integrated in Rc for 1200s in five pointings.

Visual comparison to the DSS reveals no optical transient. Through
calibration to five USNO A-2.0 stars, we estimate the (S/N=3) limiting
magnitude to be Rc=19.2.
