What is This?

Scott Vincent

I noticed your web site and thought I would forward these contrail photos. I've not seen any like this before, but maybe I'm just unobservant and it is a natural phenomenon.

Please let me know if you find them interesting or if they're just a common occurrence as a result of atmospheric conditions. They were taken on 20 November 2005 in the UK during a period of very high pressure.

Readers: Scott's photographs show trails that are unlike any contrails I have ever seen. Have you seen or photographed anything resembling this? Please send comments to "Backscatter." Photos are especially welcome. Editor.


Wanted: Gallery Contributions

Contributions to "Gallery" are welcomed. Please submit sharp JPEG photographs and a caption of from a few sentences to several paragraphs. Be sure to include the full name(s) of any people in your submission. To the best of your ability, provide both the common name and the genus and species of any plants or animals. Common names are lower case, as in the live oak tree. The genus is capitalized and the species is not, as in: The live oak (Quercus virginiana) keeps its leaves during winter. Also provide information about the camera that made the photograph.

Send your contribution as an e-mail to the Editor. Place "Gallery" in the subject line. Be sure to include your full name. Attach the photograph as a JPEG.

Thank you for considering The Citizen Scientist. Editor.
