EYES TO THE SKY: All night planets Saturn, Jupiter. Overnight astronomy holiday
July 8 – 21, 2019
Mount Washington — Tomorrow, planet Saturn arrives at “opposition.” Like Jupiter last month, Saturn is now coming into position opposite the Sun in Earth’s skies. Saturn rises in the southeast at 8:20 p.m. on the 9th – 8:23 p.m. tonight, the 8th – opposite sunset in the northwest within seconds of 8:31 p.m. both evenings. All summer, Saturn will be visible at least until midnight, before setting in the southwest as the Sun rises in the northeast. Tomorrow morning, the 9th, Saturn sets at 5:37 a.m.; sunrise is at 5:26 a.m. and the precise moment of opposition is 1 p.m. EDT.
Saturn is at its brightest for the year. The ringed planet’s apparent magnitude is 0.05. When compared to Jupiter, at magnitude -2.54, Saturn is not much brighter than many neighboring stars. Note that the smaller the magnitude number the brighter the celestial object.
Saturn rises about four minutes earlier every day. On the 21st, the planet rises at 7:29 p.m. opposite sunset at 8:24 p.m, Saturn sets at 4:42 a.m. on the 22nd, when sunrise is at 5:36 a.m. Alan MacRobert, senior editor of “Sky and Telescope” and “Star Date” columnist, writes: “Two weeks on, you’ll find that Jupiter and Saturn are noticeably westward (to the right) of where they appeared at the same time of night two weeks earlier. Remember the formula for the turning of the sky: Looking two weeks later is the same as looking one hour later.”
