Swank (NASA/GSFC) report:\n\nRXTE re-observed GRB 030329 for a total of 3.9 ks\nstarting at March 30.724 UT (about 1.240 days after the burst).\nThe flux was about 0.9e-11 ergs/s/cm**2 in the 2-10 keV band\nor about 15 times weaker than during the RXTE\nobservation the previous day (Marshall and Swank, GCN 1996).\nThe total light curve is well described by a simple model\nin which the flux decays as t^(-1.5).\nMore complicated models are also consistent with the \nsparsely sampled data. For example, \na model in which the decay rate increases \nfrom  t^(-1.1) at early times (Burenin et al., GCN 2024) to\nt^(-1.934) at late times (Garnavich et al., GCN 2018;\nSmith, GCN 2019; Halpern et al., GCN 2021)\nfits the data if the break occurs 0.54 days after the burst.",
