Descripción
PG 1351+64 is a bright radio quiet quasar (z = 0.088, mV
≅ 14). IUE observations obtained within few months in 1982 - 1983
showed variations in the 1200 - 2000 Å band up to a factor of 2.
Since then the object has been monitored regularly. The observations of
1984 - 1986, including also archival data, have more than doubled the
number of available spectra in the UV. In particular the source was
found in its brightest state, both in the optical and UV bands, in 1986
February.
