Grand Canyon Star Party – June 2024

The Grand Canyon Star Party (GCSP) is held on the South Rim in northern Arizona’s Grand Canyon National Park in June every year around the time of the new moon. All amateur astronomers (must register using below information to attend) and the interested public of all ages are invited (no registration required)! Bring your telescope and enjoy the camaraderie. But you don’t have to have a telescope to come and enjoy the beautiful Arizona night skies. You DO need to reserve a room or campsite and make your travel arrangements early. See Accommodation Information for details. A visit to the breathtaking Grand Canyon is an unforgettable and fabulous vacation for families, singles, and seniors. Add a week of dark Arizona skies, lots of friends, fun, and astronomy education, and you have a recipe for perfection!

Planets of the Month: April 2023

by Erich Karkoschka

Mercury is visible well at dusk until the 19th. It even sets past the end of astronomical twilight around the 11th, when it is at greatest elongation from the sun. Afterwards, it shows a small crescent in a telescope.

Venus is high up at sunset and sets more than three hours later. On the 10th, it is only 2 degrees from Pleiades, a nice sight in binoculars.

Mars is very hight at sunset. On the 14th it passes only 9 arc-minutes from third-magnitude star Mebsuta in Gemini. Then it aims for Pollux, the brightest star in Gemini.

Saturn is visible just before dawn in the southeast.

The first minor planet (1) Ceres is an easy binocular object near the tail of Leo.

The moon is close to bright Venus on the 22nd and 23rd and then even closer to Mars on the 25th. It causes a hybrid (total/annular) solar eclipse on the 20th, visible in and near Australia. The same evening it can be spotted with binoculars in Tucson in bright twilight, with Mercury nearby. The moon follows with an almost partial lunar eclipse at noon on May 5th. We are only one year away from the total solar eclipse of April 8, 2024 with more than 4 minutes of totality going from Mazatlan in Mexico through Texas to the Great Lakes.
