[9.06] ROLO Multi-Color Observations in the Visible and Near-IR

J.M. Anderson (USGS)

The Robotic Lunar Observatory (ROLO) is an automated telescope designed for low-resolution absolute photometry of the Moon. Separate CCD and HgCdTe array instruments with nearly identical fields of view of 35' \times 35' are used to image the Moon and a set of standard stars during the two weeks surrounding each Full Moon. Wavelength selection from 350~nm to 2.4~\mathrm{\mu m} is provided by 32 narrowband filters. Analysis of these Lunar data continue as part of NASA's Earth Observing System (part of the Earth Science Enterprise) spacecraft calibration program. Photometry of h and \mathrm{\chi}~Persei was obtained as part of an instrument characterization program. Observations of other objects such as the Orion Nebula have also been made to explore the wide-field imaging potential of the ROLO instrumentation.
