  1. PHASE FUNCTION OF LUNAR COLOR RATIO Yu. I. Velikodsky, Ya. S. Volvach, V. V. Korokhin, Yu. G. Shkuratov, V. G. Kaydash, N. V. Opanasenko, M. M. Muminov, B. B. Kahharov Institute of Astronomy, Kharkov National University, Kharkjv, UkraineAndijan-Namangan Scientific Center of Uzbekistan Academy of Sciences, Andijan city, Uzbekistan 2MS3, Moscow, 10-14 Oct., 2011

  2. PHASE FUNCTION OF LUNAR COLOR RATIO C(λ1/λ2)=A(λ1)/A(λ2) Lunar samples: phase curves of color ratio C(620/430 nm)

  3. Observations: • Maidanak (Uzbekistan), Aug-Oct 2006 • 15-cmrefractor (guide of Kharkov telescope) • Canon EOS 300D • 20,000 images (130 GB) • Phase angles 1.6–168° • "R": 0.61 µm, "G": 0.53 µm, "B": 0.47 µm
