Sigma Xi dinner-February 24, 2000

Texas A & M - Commerce
Campus chapter of Sigma Xi
Thursday February 24, 2000
6:00pm, Rayburn Room, Memorial Student Center

A dinner meeting, with after dinner talk by

Dr. Keith West
of Texas A& M University - Commerce
(Physics)

Dr. West's talk is titled "Variations of Ion Composition in the Low-Latitude Topside Ionosphere: Temporal, Longitudinal, and Solar Cycle Effects"

Abstract: The composition of the low-latitude topside ionosphere is highly influenced by neutral winds at lower altitudes. The effects of these neutral winds vary with local time and season, as well as with longitude and solar cycle. A brief examination of the average large scale variations of ion composition over a portion of a solar cycle is made for all longitudes at postsunrise/postsunset times. The data were taken in situ and show conditions at equinoctial and solsticial conditions.

Dinner will begin at 6pm; the talk should begin around 6:30 or 6:45pm. The cost of the dinner will be supplied later (less than $10). While you can pay at the door, we need to know who will be going to the dinner by Tuesday, February 22 some time in the morning, for catering purposes. (You can email Dr. Chourasia a note here, or phone him at 886-5485.)
