Abstract

An SSP-4 photometer and filters transformed to the Mauna Kea J and H system were used in measuring the brightness of Saturn + rings (hereafter “Saturn”) in 2014 and 2015. The selected normalized magnitudes extrapolated to a solar phase angle of 0° are J(1,0) = ‒10.67 ± 0.02 and H(1,0) = ‒10.40 ± 0.02 in 2014 and J(1,0) = ‒10.76 ± 0.02 and H(1,0) = ‒10.51 ± 0.01 in 2015. These appear to be the first published J and H magnitude values for Saturn.
