  Time-domain astrophysics benefits from extreme-latitude sites, which can
combine intrinsically extended nighttime with good sky conditions. One such
location is the Polar Environment Atmospheric Research Laboratory (PEARL), at
80 degrees North latitude, on the northwestern edge of Ellesmere Island,
Canada. Experience gained deploying seeing monitors there has been incorporated
into an automated system called "Ukaliq" after the common arctic hare, which is
also very well suited to its local environment. Even with modest aperture, high
photometric reliability may be achieved using simple adaptive optics together
with observing strategies that best fit the unique set of advantages available
at PEARL: excellent image quality maintained during many clear, calm, dark
periods of 100 hours or more. A potential multi-year search for gravitational
microlensing of quasars with Ukaliq helps illustrate this niche in the era of
large wide-field survey facilities.
