The timescale for injection of fresh nucleosynthetic material and for the formation of the first solids in the early solar system is determined by the existence and abundance of short-lived nuclei. The presence of live ^(26)Al with ^(26)AI/^(27)AI ~ 5 x 10^(-5) in numerous CAI from C2 and C3 meteorites places an upper limit to this timescale of ~ 8 x 10^6 y but the lower limit is poorly constrained.
