Subject:	astro-ph
Abstract:	HQM is an optical broad-band photometric monitoring program carried out since Sept.~1988. We use a CCD camera equipped to the MPIA 1.2$,$m telescope. Fully automatic photometric reduction relative to stars in the frames is done within a few minutes after each exposure, thus interesting brightness changes can be followed in detail. The typical photometric error is 1--2,for a 17.5,mag quasar. We here present lightcurves already evaluated but not shown in Paper I. We also discuss existing literature data.
