Astronomically, retrogrades occur when Earth passes or is passed by other planets, creating the illusion of backward movement.  Astrologers analyze how this motion affects us personally and collectively.  Lelonni Campbell will discuss each planet's retrograde effect including the effect on the birth chart.  This is an in-person presentation that can also be viewed at home via Zoom.  In-person: No registration required.  For additional inquiries, please call the library at 631-567-5079 or visit our website.
