Here is a real-time full color view of the Earth from the Himawari satellite, updated every half hour or so. This geostationary weather satellite is stationed over the longitude of Japan. The view is complete with orange sunglint off the ocean. You can click on the link to see the latest update.

We can look around for the full resolution real-time data archive that would be about 11000 pixels wide. -------------------- Steve [ my home page and planetary maps page ]

Pretty neat Sean - I thought I was out there in space and wondered if I would fall toward the Earth.
The sun glint (and twilight effect) is really neat to see and a good test for sun glint modeling. On the limb itself we quickly transition from the orange glint color to the blue atmosphere. Perhaps that's the way it really looks. I would suspect the limb edge would be slightly muted and we might see a few clouds or haze layers silhouetted in front of the blue atmosphere? Hard to get a consensus considering other imagery, and LEO imagery might look somewhat different. Perhaps more resolution would be needed to tell for sure. Another note is that Himawari wavelengths are a bit different from CIE peaks, helping to explain why Australia looks on the brown side. -------------------- Steve [ my home page and planetary maps page ]
