I can't say what Al Gore may or may not have been expecting, but I've been waiting for this. Although I didn't expect it to happen so soon after the satellite became operational.
ReplyDeleteThe nearly full moon disappearing and emerging from behind the full Earth will also provide some notable images in the coming weeks or months.
Just plain cool!
ReplyDeleteAnd there's now another (single) image available showing Africa (no Moon).

PS, anyone seen a stereo pair using a couple of those images including the Moon? Ought to be ...
ReplyDeleteDeos the sattellite meander fast enough within the Lagrangian garavity well to do stereo?

ReplyDeleteNo need for the satellite to move since the planet is moving. Take two successive images (pick ones without the obscuring Moon) and make one left and the other right.
Same works for the Moon because the Moon wobbles a bit:

I thought DSCOVR was going to have more imagery up by the end of September. Well, there's a few hours left.
I also hoped, though without any encouragement, that DSCOVR would make the raw images available, as so many other publicly financed projects do -- Cyclops has the Saturn system raw imagery easily available. They also have a link for amateur imagery made from the official images -- time lapse movies made from still sequences.
Surely we could be doing that with the multispectral channel images from DSCOVR every day.
p.s.: "All in all, about 59% of the moon is visible from Earth over the course of a year"
