Dr. Gerard Williger will discuss things which change in the sky.
Most stars in the sky do not change much with respect to each
other. Many other things do: eclipses happen, planets move and
some stars flare up or get dim. We will review transient
phenomena through history, and connect them to research
today, including the Large Synoptic Survey Telescope, to
which Kentucky is contributing. We will also give special attention
to the big solar eclipse next August.

Parking is free in the Speed Engineering lot across the street from 7:30pm
