Overnight excitement at HRPO as we open to witness one of nature’s most spectacular events! While in the constellation Libra♎, the Moon will enter the Earth♁’s shadow, turning darker and darker—and then??? The actual color can range from dark brown to red to bright orange to yellow, depending on the current state of the Earth♁’s atmosphere. Don’t miss it. This event begins on Sunday evening and ends on Monday morning.

THE DANJON SCALE
Want to be a scientist for a night? Within fifteen minutes of mid-eclipse, note the color of the Moon. Memorize what you've seen and compare the color to the scale below…
L0 = very dark eclipse: Moon almost invisible (especially at mid-totality)
L1 = dark eclipse: gray or brownish in coloration / details distinguishable only with difficulty
L2 = deep red or rust-colored eclipse: very dark central shadow, while outer edge of umbra is relatively bright
L3 = brick-red eclipse: umbral shadow usually has a bright or yellow rim
L4 = very bright copper-red or orange eclipse: umbral shadow has a bluish, very bright rim
Make sure you form your own assessment of the totally eclipse Moon's color before discussing it with anyone else.
Current predictions from Peat suggest six visible passes from 8:13 pm to 9:24 pm, the brightest of which is currently listed as magnitude -2.5! These pass times will be included in a schedule PDF at the bottom of this page after the pass values are refined over the next few weeks.
