Abstract

We report measurements of the light curve of the variable Galactic Center source IRS16SW. The light curve is not consistent with an eclipsing binary or any other obvious variable star. The source may be an example of a high mass variable predicted theoretically but not observed previously. Subject headings: stars:individual (IRS16SW), stars:variables:other, Galaxy:center 1.
