Lunar Eclipse Phenomena: Modeled and Explained
Anthony Mallama
A model based on celestial geometry and atmospheric physics predicts the dimming and the color of lunar eclipses. Corresponding visual magnitudes and color indices for eclipses fro…
Starlink Satellite Brightness Before VisorSat
Anthony Mallama
The mean of 830 visual magnitudes adjusted to a distance of 550 km (the operational altitude) is 4.63 +/-0.02. The data on DarkSat, the low-albedo satellite, indicate that it is fa…
Computing Apparent Planetary Magnitudes for The Astronomical Almanac
Anthony Mallama, James L. Hilton
Improved equations for computing planetary magnitudes are reported. These formulas model V-band observations acquired from the time of the earliest filter photometry in the 1950s u…
The Mid-IR Albedo of Neptune Derived from Spitzer Observations
Anthony Mallama, Liming Li
Mid-IR albedo values of Neptune are derived from Spitzer Space Telescope measurements reported by Stauffer et al. (2016). The method of this derivation is described and the results…
The Spherical Bolometric Albedo of Planet Mercury
Anthony Mallama
Published reflectance data covering several different wavelength intervals has been combined and analyzed in order to determine the spherical bolometric albedo of Mercury. The resu…
The Geometric Magnitude and Albedo for the Globe of Saturn
Anthony Mallama, Hristo Pavlov
Saturn's geometric magnitude and albedo were determined by Mallama et al. (2017, Icarus 282, 19-33). That analysis depended largely on photometric data obtained when the ring syste…
Comprehensive Wide-Band Magnitudes and Albedos for the Planets, With Applications to Exo-Planets and Planet Nine
Anthony Mallama, Bruce Krobusek, Hristo Pavlov
Complete sets of reference magnitudes in all 7 Johnson-Cousins bands (U, B, V, R, I, Rc and Ic) and the 5 principal Sloan bands (u', g', r', i', and z') are presented for the 8 pla…
The Secular and Rotational Brightness Variations of Neptune
Richard W. Schmude, Ronald E. Baker, Jim Fox +3
Neptune has brightened by more than 10% during the past several decades. We report on the analysis of published Johnson-Cousins B and V magnitudes dating back to 1954 along with ne…
Large Brightness Variations of Uranus at Red and Near-IR Wavelengths
Richard W. Schmude, Ronald E. Baker, Jim Fox +2
Uranus is fainter when the Sun and Earth are near its equatorial plane than when they are near the projection of its poles. The average of the absolute values of the sub-Earth and…
The Old and New Meanings of Cloud 'Belt' and 'Zone': A Study of Jovian and Saturnian Atmospheric Banding
Anthony Mallama
The brightness of cloud bands on Jupiter and Saturn as a function of latitude is reported. Bright Jovian bands near the equator are located in regions of anti-cyclonic circulation…
