CRRES NEWS FEBRUARY 10, 1991 The next window for CRRES release is February 12, 1991 at the discrete times 0315, 0345, 0415, 0445, 0515, 0545, 0615, 0645 and 0715. [NOTE - THIS IS UT; subtract 6 hours for CST, etc...PR] For this window G-6 [Lithium] will be prime. The Feb 14 release has windows every half hour 0430 - 0830 UT. For the February 14 window, G-8 [large Barium] will be prime since we have Millstone Hill Radar coverage only for the first hour of the window (A matter of ability to see the field-line foot, not a matter of scheduling). The most recent orbital elements and predicted elements for February 12 are listed below, plus look directions for Houston. David L.
