The astronomical highlight of 2017 is the Great American Total Solar Eclipse on August 21. This is the first total eclipse visible from the continental USA in 38 years. For complete details on this highly anticipated event, see: 2017 Total Solar Eclipse (EclipseWise.com).

For information on all solar and lunar eclipses this year, see: Eclipses During 2017.

The Calendars of Astronomical Events were all generated by a computer program I wrote (with THINK Pascal running on a Macintosh G4) using Astronomical Algorithms (Jean Meeus).

  1. Mr. Eclipse,
    Thank you for your great information. I am an armature eclipse photographer; for sure. Did put a solar filter together, used your settings and did get some eclipse shots in Florida. Read your stuff from Earth Sky. Was very helpful. Enjoyed it a great deal. Felt like I could have helped the NASA ppl talking about the eclipse on tv…hey, they did not tell ppl to look for those bailey beads! Thanks again…
