We report on the disk-averaged absolute brightness temperatures of Venus measured at four microwave frequency bands with the Cosmology Large Angular Scale Surveyor (CLASS). We measure temperatures of 432.3 \pm 2.8 K, 355.6 \pm 1.3 K, 317.9 \pm 1.7 K, and 294.7 \pm 1.9 K for frequency bands centered at... Show more
