Overview

• The trio squeezes into roughly a one-degree patch of sky, presenting an almost straight line for some locations and a tight triangle for others.
• A slender 5–6% waning crescent sits beside a very bright, ~89%-lit Venus with Regulus nearby, all low in the east-northeast before dawn.
• The Moon will briefly cover Venus for observers in the extreme northwestern Canadian Arctic under twilight, with a daytime occultation visible across the North Atlantic, continental Europe and northern Africa.
• Regulus will also be occulted by the Moon for a remote band of northern Siberia near Dudinka.
• The spectacle is short-lived as the Moon shifts by about a diameter per hour, separating from Venus and Regulus by Sept. 20.
