Abstract:
Recent daytime images of the ISS have led the authors to reevaluate the challenges of daytime imaging. Daytime images of the ISS and other satellites illuminated by Earthshine, at solar phase angles exceeding 150° are presented. These images were taken with a 2 effective aperture. The advantage of Earthshine for daytime custody is that in general, the larger the solar phase angle, the greater the Earthshine illuminating the near side of the satellite. Additionally, the presentation will discuss the strength of the Earthshine contributions, such as optimal wavebands and the spectral albedos of various terrain types, and how these need to be considered to determine the feasibility of future daytime imaging.
