The Forbush-effect that was observed on the periphery of interplanetary disturbances in July 2005 is discussed. The intensity of galactic cosmic rays has decreased by about 2% on July 16 and then Forbush effect reached 8% at end of day July 17 in many ground monitors. The perturbation was small in the near-Earth space, and it could not provide the value Forbush effect. We discuss observations of two solar flares (M9.1 and X1.2 ) that were occurred near the western solar limb in July 14, 2005. There is the fact that the second flare’s CME was characterized by a speed of about 2300 km / s at the beginning of ejection. Brushing the remains of previous ejections, the CME has formed steep western front of the interplanetary disturbances, in which the giant Forbush effect has been in the west line of the Sun-Earth.
