Arctic eclipse

Reason: View of a total solar eclipse on earth as seen from NASA's Terra satellite. Covers the Arctic Ocean, northern Norway, and northwest Russia. The affected area was dark for two minutes during the eclipse. Satellite path was nearly perpendicular to the eclipse. Spectacular view of the umbra and penumbra from a unique perspective.

Question: Which way is north? Rmhermen (talk) 18:49, 16 August 2008 (UTC)[reply]
- Looks to be at right. Adding an animation of the eclipse for comparison. Durova^Charge! 19:27, 16 August 2008 (UTC)[reply]
Support I love the shown difference between the umbra and penumbra. Spencer^T♦^C 21:38, 16 August 2008 (UTC)'[reply]
Support Waaaay cool! Clegs (talk) 01:33, 17 August 2008 (UTC)[reply]
Note when adding additional images, it's best to add them directly below the code for the original image to avoid creating whitespace in the middle of the nomination. See this diff and the effect it has. Raven4x4x (talk) 02:16, 17 August 2008 (UTC)[reply]
Support, nice find. The little GIF anim confuses me a bit though. The relative sizes of umbra and penumbra in the gif and in the sat image seem to be different. --Dschwen 15:40, 18 August 2008 (UTC)[reply]
- The penumbra looks different in an animated representation v. an actual photo of the eclipse because small percentages of obstruction don't cast an obvious shadow. Durova^Charge! 21:05, 18 August 2008 (UTC)[reply]
  - So, essentially all we are seeing here is penumbra, right? --Dschwen 21:51, 18 August 2008 (UTC)[reply]
    - What makes you suppose that? Durova^Charge! 21:55, 18 August 2008 (UTC)[reply]
      - What I'm wondering is, where is the umbra on the picture. I don't really get a sense of scale here. From the gif it looks like the umbra is just a tiny spot. But on the satellite image the black area is huge. Is the umbra somewhere in the blackness? --Dschwen 22:18, 18 August 2008 (UTC)[reply]
        That's the difference between schematic representations, earth-based photography, and satellite photography. Unless the NASA caption has very misleading wording, yes this does include totality. Durova^Charge! 22:34, 18 August 2008 (UTC)[reply]
