The activity profile of the new filament in the Perseid meteor stream and its 1986-1994 levels were analyzed from Ondřejov radar observations. The filament was first detected in 1986 at its minimum activity level. Its maximum flux was observed in 1993. A secondary maximum appeared in the period 1988-1989. The cross-section profile of the new cloud shows an activity peak at L⊙ = 138°.87±0°.04 (equinox 1950.0).
