Hi Bjorn, I've been gone on vacation for 5 days so I don't know if your question below was adequately answered yet, but there is no discrepancy between the two pictures. As I pointed out last week in one of my posts, while the trajectory appears to be parallel to the Kazakhstan/Russian border in

[meteorite-list] What was the true azimuth of the Russian meteor?

List, There seem to be posted two quite different images to the list about the compass direction from where the meteor came on Friday 15, morning (local). Obviously one of them must be wrong. Surprising if the weather image is wrong, how did that come about? Which one is closest to the direction

The meteor came from the east (where the Sun was rising). Where did you get the image at the bottom? Everything I have seen about this has said or showed (in videos) that it came from near the Sun and was travelling to the west. Bob -Original Message- From:

Hi Bob The bottom image was posted to the list with two others showing closer up projection on a map of The Chelyabinsk area. They all three show the roughly 120 degree azimuth entry. They seems to be detailed and some level of work behind. The Sun at this time would rise in the region at 100-110

Hi Bjørn, In the videos, the meteor is first seen above and to the left of the rising sun, so that would mean that it was further north than the rising sun. If you estimate the sun to be rising between 100-110 degrees azimuth, then the meteor would be less than 100 degrees, so the 80 degree

Bob, The link below support strongly (from Robin Whittle post, thanks to him) the trajectory of the lower image in my first link. From the videos it is found that the bolide travelled almost right overYemanzhelinsk which is south of Korkino, which are two suburbs south of Chelyabinsk. Then
