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 degree azimuth, I estimate. The image come from a posting to the list about a day ago, titled: Russian progress on trajectory posted by Robin Whittle
Bjørn Sørheim ------------------------------------- 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.

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 used by Esko to compute the orbital elements? And which is the true direction? Would be important to clarify this. North is up in both images. Chelyabinsk is in the mid top at the lower one, and near the middle in the top image. The top image suggest azimuth 80 degree, while the lower about 120 degree. Here is a link to the two differing directions stitched together: home.online.no/~bsoerhei/astro/meteor/metlist/twoaz.jpg Bjørn Sørheim ______________________________________________ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
