Abstract:
    We report on extensive photometry of DK Lac obtained during the
    interval 1990-2009, which includes a 2mag low state during 2001-2003.
    Much of the photometry consists of exposures obtained with a typical
    spacing of several days, but also includes 26 sequences of continuous
    photometry each lasting 2-7hr. We find no evidence for periodicities
    in our data.

Description:
    Our DK Lac photometry is of two types. First, we have long-term
    monitoring at a typical cadence of two to three observations per week,
    obtained mostly with the local Indiana automated photometric
    telescopes.
