September 2022 Interested in learning more? If you live in northwestern lower Michigan check out the Grand Traverse Astronomical Society. More information on visible planetary and other events are available on Bob Moler's Ephemeris Blog the day of the event. The blog contains Monday-Friday program transcripts, most with illustrations and additional information. I dug through the IPR web archives and found these: Bob Moler looks back at 40 years of 'Ephemeris'I’m interviewed about all things astronomical prior to the August 21, 2017 eclipse. Photo, text, and audio. -------------- Extra! My report on the Great American Eclipse of August 21, 2017, with added animated GIF of the sky at the totally eclipsed Sun, watching the shadow pass over.

Events Calendar by Fred Espenak and Sumit Dutta (NASA’s
GSFC), If you go to the above site you can print out a list like the above for the entire year or calendar pages for your time zone. Note that the site is now kept up for archival purposes. Fred Espenak retired from NASA several years ago and has his own site, AstroPixels, which contain much the same information: http://astropixels.com/almanac/almanac.html. However, he doesn’t adjust for Daylight Saving Time.

Free SoftwareStellarium is a fabulous planetarium program with a very realistic sky and simple controls. They've added some features in the latest version (0.22.0) and new rendering engine that may not be compatible with older computers without using command line options. See the Stellarium User Guide (pdf) under Command Line Options for what to try. https://stellarium.org. There’s a web based version of Stellarium. It’s pretty much bare bones, but works much like the computer version. It’s located here: https://stellarium-web.org. Cartes du Ciel (Sky Charts) is a great telescope companion. I use it to create finder charts for comets and calendar lists of twilight times for the monthly preview on my blog. I use it for my weekly look at the planet telescopic appearances. It can be downloaded from http://astrosurf.com/astropc/. Virtual Moon Atlas is a great tool for reference at the telescope or desk. http://www.astrosurf.com/avl/UK_index.html. Celestia is a great 3D simulator of solar system objects and beyond. However it has not been updated in a while. http://www.shatters.net/celestia/ Hallo Northern Sky is an interesting planetarium program. It seems not as polished as Stellarium, but has some cool features. I use it when planning star parties as a quick way to see what would be visible because it loads quickly. http://hnsky.org/
