PROGRAM_ABSTRACT_BEG
We propose 25 hours of 2023A time with the newly available MIRSI and its optical camera [MOC] to measure the diameters and albedos of at least 25 near-Earth Objects. By observing simultaneously infrared and optical wavelengths, we will derive high-quality diameters, albedos, and colors [taxonomies] for all of these NEOs. NEOs' spectral energy distribution peaks around 10.5 microns; thus, our observations will be performed using MIRSI's N-band. We successfully performed MIRSI and MOC observations in previous semesters, detecting more than 15 NEOs above 250~mJy with simultaneous r-i-z-band imaging. We have built Python routines to reduce, calibrate, and analyze the acquired data. This semester's allocation will be part of a large-scale survey seeking to constrain the physical processes occurring in smaller sizes in near-Earth space. These NEOs observations will also provide mission support since we include object 98943, the next target for the Hayabusa2 spacecraft, in which physical properties such as colors, albedo, and diameter are needed. In addition, this survey will include objects as small as 100 meters for which physical properties have not been measured.
