The B- and V-filter brightness values of the eclipsed Moon on January 21, 2019 were measured. The brightness values near mid-eclipse are B = –0.33 (0.15) and V = –2.07 (0.05) magnitudes. Uncertainties are in parentheses. The V-filter brightness near mid-eclipse compares well with a recent lunar eclipse model by Mallama; however, the measured B – V value [1.74 (0.16) magnitudes] is below the predicted value of 3
