We present the results of 5 BeppoSAX AO1 Core Program observations of 3C 273 performed in Jan. 1997 and compare them in detail with data obtained during the satellite Science Verification Phase (SVP), in Jul. 1996 (Grandi et al. 1997). 3C 273 was about 15% brighter in the first 1997 observation than in the last one, and, on average, a factor 2 brighter than the SVP observation. A count rate variation in the 2–10 keV band of ≃ 12% in ∼ 0.5 day was clearly detected during the last of the four… Expand
