Abstract
Ground-based counts and colours of faint galaxies in the U and R bands in one field at high Galactic latitude are presented. Integrated over flux, a total of 1.2 × 10^5 source deg^(−2) are found to U = 25.5 mag and 6.3 × 10^5 source deg^(−2) to R = 27 mag, with d log N/dm ∼ 0.5 in the U band and d log N/dm ∼ 0.3 in the R band. Consistent with these number-magnitude curves, sources become bluer with increasing magnitude to median U— R= 0.6 mag at 24
