Eclipse Highlights Not To Miss
Prepare for the bizarre. First-time eclipse observers should anticipate several unique phenomena during a total solar eclipse, for you don't want to miss multiple sensory features that contribute to the indescribable awe. The spectacle entails more than a disappearing sun and its signature corona. If you prepare for these subtleties in advance, your total solar eclipse experience will be vastly more rewarding.
Michiana Astronomical Society (MAS) President Bruce Miller kindly recorded Eclipse Blitz (https://youtu.be/WLYhoFazaGM) in which I suggest ways amateur astronomers and educators can engage the public with eclipse-related activities for all age groups. I then delve into the multiple eclipse highlights that can easily be missed amid the distractions of approaching totality.
Though I rapidly blast through slides in a survey of topics that observers can pursue on their own, I show in more detail the bizarre nature of lighting and shadows seen just before and after totality. For example, most of your life the sun is a disk in the daytime sky, but on Eclipse Day you have fleeting minutes when the sun segues from a disk to a sliver to a point. Not only does the brightness diminish, but the characteristic of the light itself and your eye's response yield bizarre visual effects. You can demonstrate this beforehand, then hopefully witness it live on April 8, 2024.
Thanks go to Bruce Miller, MAS colleagues, and visiting guests who attended the session both in-person and online. I appreciate your enthusiasm, suggestions, and kind words. Thanks also to Gordon Telepun (Solar Eclipse Timer) and others from whom I borrowed images and content for educational purposes. In some instances where I used wording that could yield misconceptions, I edited them out of the YouTube video. I recommend you fact check me and do your homework.
May you have clear skies and be well prepared to seize the day that day disappears.
