  In 1998 the EXPORT team monitored microlensing event lightcurves using a CCD
camera on the IAC 0.8m telescope on Tenerife to evaluate the prospect of using
northern telescopes to find microlens anomalies that reveal planets orbiting
the lens stars. The high airmass and more limited time available for
observations of Galactic Bulge sources makes a northern site less favourable
for microlensing planet searches. However, there are potentially a large number
of northern 1m class telescopes that could devote a few hours per night to
monitor ongoing microlensing events. Our IAC observations indicate that
accuracies sufficient to detect planets can be achieved despite the higher
airmass.
