If you have a chance to step outside tonight, be sure to catch a fabulous view of the International Space Station passing overhead. Starting at 8:00 pm in the SW, the ISS will become visible, eventually passing overhead and into the ENE sky before passing into Earth’s shadow (orbital sunset) at 8:05 pm. This will be a stunning pass, certainly not one to miss! Additionally, the ISS has just begun the current cycle of evening passes over the US. Stay up to date with pass times on the Frosty Drew Observatory website for daily passes applicable to Southern New England and generally the Northeast. For pass times specific to your location, visit NASAs Spot the Station.

This coming Monday, September 23, 2019 at 3:50 am ET, Earth will reach the point in our orbit where the Northern Hemisphere is neither tilted towards nor away from the Sun. This is the Autumnal Equinox, and hails the start of autumn in the Northern Hemisphere. Earth is tilted 23.4° on its axis, and depending on where Earth is in our orbit around the Sun, will determine if that tilt is towards the Sun or away from the Sun. This is what gives Earth its seasons. On the Summer Solstice, Earth reaches maximum tilt (23.4°) towards the Sun, skip ahead six months and we have the Winter Solstice, when Earth reaches maximum tilt (23.4°) away from the Sun. March and September bring the equinoxes, when Earth’s axial tilt is neither toward nor away from the Sun. On these two days (including Monday), all locations on Earth will experience an equal amount of daytime and nighttime. If you stand at the North Pole or South Pole, the Sun would ride the horizon all day. After the Autumnal Equinox, nighttime periods become longer than daytime periods on a daily basis in the Northern Hemisphere. So celebrate the start of Autumn and all the leaf-peeping, pumpkin eating craziness that comes with the switch into the darker side of the year, and have a Happy Autumnal Equinox from all the astro geeks at Frosty Drew Observatory!
