A total of 42 full-disk brightness measurements of our Moon are reported. These measurements include the entire lunar disk including the Earthlit portion. All measurements were made on the Johnson R (red) and I (infrared) system and were fitted to cubic equations. The results are summarized in this report. The selected normalized magnitudes of the Moon are R(1,0) = -0.70 ± 0.10 and I(1,0) = -1.12 ± 0.06. The selected geometric albedo is 0.18 ± 0.01 for the Johnson R and I system.
