Title: THE CALSPEC STARS P177D AND P330E

Multicolor photometric data are presented for the CALSPEC stars P177D and P330E. Together with previously published photometry for nine other CALSPEC standards, the photometric observations and synthetic photometry from Hubble Space Telescope/STIS spectrophotometry agree in the B, V, R, and I bands to better than ∼1% (10 mmag). Photometry over the 1986 to1991 period indicates that BD+17°4708 brightened by ∼ 0.04 mag.
