Pittori, P.Giommi, L.A.Antonelli (ASDC), and L. Salotti (ASI) report:\n\n\nFurther analysis of the AGILE GRID (Gamma-Ray Imaging Detector) data of \nGRB 070724B (Feroci et al. GCN 6668) confirms the absence of significant \nemission at energy above 50 MeV. Only one photon consistent with the \ndirection of GRB 070724B has been detected by the GRID in a ~100 second \ninterval around the time of the burst. This is consistent with the \nmeasured background rate.\n\nWe note that a gamma-ray flux similar to that observed with EGRET from \nGRB930131 (Sommer et al.1994, ApJ 422, L66), would have given about 20 \ncounts in the GRID in the same time interval.\n\nWe also analyzed the data of the AGILE Mini-Calorimeter, which provides a \nnearly whole-sky monitor in the energy range ~0.35-3 MeV (no directional \ninformation), without finding any statistically significant count rate \nincrease in correspondence of GRB 070724B.\n\n[GCN OPS NOTE(26jul06): Per author's reuqest, the Subject line was changed\nfrom \"070734B\" to \"070724B\".]",
