  Time resolved photometry of the long-period intermediate polar V1062 Tau
confirmed the presence of the previously reported orbital and spin periods, and
revealed the presence of a third one, corresponding to the beat of the two.
While the orbital periodicity was present throughout our data, only one of the
shorter periods was detectable at any given time. On a time-scale of ~90 days,
the short-period modulation in the light curve of the star changed three times
between the spin period and the beat. On longer time-scales, we report two
outbursts of V1062 Tau (the first to be recorded for this object) - both of
which were probably short, low-amplitude ones (dm ~1.2 mag). Our data also
suggest a brief low state phase in 2002 Jan. Thus, this system joins two
exclusive groups of intermediate polars: those undergoing short outbursts, and
those having low states. We propose that the alternations between the short
periods that modulate the light curve were caused by changes in the accretion
mode, from disc-fed accretion, to disc-overflow accretion. We further suggest
that these changes may have been triggered by changes in mass-transfer rate,
which were manifested by the low-state/outburst activity of the system.
