DSCOVR images the Moon crossing in front of the Earth
Cool video time! Images from the recently launched Deep Space Climate Observatory (DSCOVR) have been assembled to create a short movie showing the Moon transiting across the face of the Earth.
I have embedded the animation below the fold.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

A friend of mine worked on the EPIC camera, back when the satellite was known as Triana, or sometimes “GoreSat.” He told me that there would be a brightening in the center of the Earth, because the sunlight would be reflected directly back at the camera from a region perpendicular to the direction of the light’s source (DSCOVR being at the L1 point, always directly between the Earth and the Sun).
In these images, we can see this effect. To me, it looks like the sun is looking at itself in a really dull convex mirror.
