Abstract
We have searched for time variability of the stars in the central 1 pc region of the Galaxy through K-band imaging and photometry. On timescales ranging from 20 seconds to a week, no time variability greater than 0.1 mag was found for about five dozen sources in this region, including the components of IRS 16 and the anomalous high velocity outflow stars. On a timescale of one year, we found that a new source near IRS 10E had brightened by at least one magnitude and detected possible variability with amplitude ~ 0.15 mag in several other sources.
