We report on RXTE observations of the ongoing outburst of the accreting millisecond X-ray pulsar SAX J1748.9-2021 (Altamirano et al. 2008, 674, 45A, see ATEL #2360 and #2407). Since the first detection of intermittent pulsations on January 27th, 2010, observations have been carried out on a daily basis. The source remained between 120 and 160 mCrab (2-16 keV - see ATEL #2407) until February 3rd, when the intensity started to decrease.
