September 27, 2015 Total Lunar Exlipse: Shadow View
From 5:45 pm to 9:50 pm PDT: See website for animated view
On the evening of September 27, 2015 in the Americas (early morning on September 28 in Europe and most of Africa), the Moon enters the Earth’s shadow, creating a total lunar eclipse, the last of four visible in the Western Hemisphere in a span of 18 months. This animation shows the changing appearance of the Moon as it travels into and out of the Earth’s shadow, along with the times at various stages. Versions of the animation have been created for each of the four time zones of the contiguous United States, as well as one for Universal Time.
All of South America and most of North and Central America will see the entire eclipse, while those west of roughly 120°W will see it in progress at moonrise. You won’t need special equipment to see it. Just go outside and look up!
The penumbra is the part of the Earth’s shadow where the Sun is only partially covered by the Earth. The umbra is where the Sun is completely hidden. The Moon's appearance isn't affected much by the penumbra. The real action begins when the Moon starts to disappear as it enters the umbra at about 9:07 Eastern Daylight Time. An hour later, entirely within the umbra, the Moon is a ghostly copper color, and this lasts for over an hour before the Moon begins to emerge from the central shadow.
The view in these animations is geocentric. Because of parallax, the Moon's position against the background stars will look a bit different for observers at different locations on the surface of the Earth. The Moon is in the southwestern part of the constellation Pisces.
Global Terrestrial Water Storage Anomoly
The gravity variations studied by GRACE (Gravity Recovery and Climate Experiment) can be used to determine ground water storage on land masses. By comparing current data to an average over time, scientists can generate an anomaly map to see where ground water storage has been depleted or increased.
GRACE Terrestrial Water Storage Anomaly colorbar. Rust colored areas show areas where ground water has decreased, and areas in blue are where ground water levels have increased. Note the significant decreases in ground water storage across most of California and all the way up the North American coast into Alaska.

Atmospheric River Reaching California
See website for animated look at flow of atmospheric water flow.
This project illustrates an atmospheric river that developed between 9th and 12th of Dec. 2014, streching across Hawaii to California based on water vapor data and IMERG precipitation data. The animations show the IMERG precipitation data over the white, cloud-like water vapor.
