Observations of A 0535+26 on August 28 with the RXTE/PCA show a rapid
rise in flux since the sources 20 mCrab detection on August 26 (ATEL #595).
An observation with mid-time of 2:15 UT had a mean flux of 90 mCrab, while
three observations between 14:20 and 18:10 UT had mean fluxes of 430, 220,
and 260 mCrab. These fluxes are based on the standard 1 rates (2-60 keV).
