  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.
