![]() ![]() At this time 12 years ago today, this tornado (upper end EF-4) was moving through Tuscaloosa.Mammatus clouds over Panama City Beach this evening… photos from Danielle Sides.Severe thunderstorm watch up for parts of West Alabama… stronger storms could produce hail and gusty winds this eve….The rim to the Umbral shadow can be very bright even bluish in colorįollow Severe thunderstorm warning issued for a small part of northern Pickens and southern Lamar counties. L=4: Very bright copper-red or orange color.Umbral shadow usually has a bright or yellow rim. Meditation during the Lunar Eclipse by Swami Vidyadhishananda Januin Announcements, Spiritual Philosophy Eclipse basics and coordinates The upcoming total lunar eclipse on the 20th/21st January is the second eclipse of 2019, following the partial solar eclipse that took place on 5th/6th January. Very dark central shadow, while outer edge of umbra is relatively bright. L=2: Deep red or rust-colored eclipse.You can make out details on the lunar surface but it is difficult. L=1: Dark Eclipse, gray or brownish in coloration.Moon almost invisible, especially mid-totality French astronomer Andre Danjon created a five-point scale in 1921 to describe the appearance of the Moon during totality. A little trigonometry and the umbral magnitude of any lunar eclipse can be calculated.Īnother way to measure lunar eclipses cannot really be predicted ahead of time. July’s total lunar eclipse umbral magnitude of 1.6, and a deeper red color than what the Americas experienced in 2019. Its measured by calculating the separation between the center of that shadow and the center of the Moon at their closest point. ![]() Any magnitude greater than 1 indicates a total eclipse and the deeper the Moon ventures into Earth’s umbral shadow the higher that number. ![]() Last night’s eclipse had an umbral magnitude of 1.2. The path the Moon takes through that shadow determines both the duration and magnitude of the eclipse. Each one is just a little different because of our dynamic atmosphere and the geometry of the shadow cast by Earth and The Earth’s umbral shadow is more than twice as wide as the Moon at that distance. You might be recalling previous eclipses you’ve seen for yourself or in photos that might have looked a little different than Sunday’s. Sunday’s total lunar eclipse produced a brilliant orangey-red Moon visible for observers from the tip of South America to Canada’s northern territories, the only lunar eclipse of 2019.
