AB: The Global Ultraviolet Imager (GUVI) is located on the NASA TIMED space craft. It is in a 630 km circular orbit with an inclination of 74 degrees. GUVI collects images of the disk and cold side limb in the UV range using a Rowland spectrograph. These UV emissions can come from several sources including radiative recombination of oxygen ions and electron and day glow due to solar excitation. These observations of the TIMED spacecraft provide a data set that can be used to study the day time equatorial anomaly. Three years of data collected by GUVI on the TIMED spacecraft have quality observations of the equatorial region in high altitude limb scans on the dayside. The combination of the space craft altitude and mirror look angle make these observations unique. In this paper we present an initial review of these data and their suitability for observing the day side anomaly and their use in observing the strength of the zonal electric field that creates the equatorial anomaly.
