  We present results from high speed photometry of a further thirteen faint
cataclysmic variables. V356 Aql (Nova Aql 1936) shows flare-like outbursts with
recurrence time scales ~ 3000 s, but no coherent periodicities. Aqr1 is an
intermediate polar with a spin period of 6.7284 min and a probable orbital
period P(orb) = 3.226 h derived from orbital sidebands. Its orbital sideband
frequencies show very variable amplitudes. The published spectroscopic period
of 2.0 h suggests that Aqr1 is similar to GW Lib and FS Aur in having an
additional periodicity of unknown origin. FIRST J1023+0038 has P(orb) = 4.7548
h with an orbital modulation of range 0.45 mag, probably caused by reflection
effect from a hot white dwarf primary; as such it may have been a nova sometime
in the past few decades. Ha 0242 is a deeply eclipsing very low mass-transfer
rate system, probably a dwarf nova of very long outburst interval, with P(orb)
= 1.792 h. GI Mon, an old nova, has optical modulations at 4.325 h and possibly
also at 48.6 min and is thus a candidate intermediate polar. AO Oct, an SU UMa
type dwarf nova, shows orbital modulation at quiescence with P(orb) = 94.097
min. V972 Oph (Nova Ophiuchi 1957) showed no flickering activity during one set
of observations, but did so at a later time, confirming the correctness of the
identification of this object, but it shows no orbital modulation. SDSS 0155 is
a deeply eclipsing polar with an orbital period of 87.13 min. SDSS 0233 shows
flaring activity but no discernible periodicity. No periodicity was found in
the new AM CVn candidate SDSS 1240. SDSS 1556 shows a periodic modulation at
1.778 h which is possibly due to orbital motion. SDSS 2050 is an eclipsing
polar with P(orb) = 1.5702 h. FH Ser (Nova Serpentis 1970) has strong
flickering activity but no detectable orbital modulation.
