Abstract

A previously unknown optical transient has been observed in the constellation Bootes. The transient flared to brighter than 5th magnitude, which is comparable to the visual magnitudes of the nearby stars pi Boo and omicron Boo. This article describes the relative astrometry and photometry work we have done regarding the transient.
