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.
