We present the first results from a pilot programme to monitor the short termoptical variability in Broad Absorption Line system QSOs. Intra-night opticalvariations of ~5% were detected on time scales of ~ one hour in QSOs 0846+156and 0856+172. Further, the mean magnitude level decreased in the two objects by~0.05 and ~0.15 magnitude respectively during the period of our observations.The observed light curves are quite similar to those previously seem in theflat spectrum radio-loud sources, especially the BL Lacertae objects, and canprovide important constraints for the origin of microvariability, and also apossible evolutionary link between the radio-loud and the radio-quiet QSOs.Comment: 12 pages Latex file uses AASTEX, 2 Postscript figures.
