Uzzo: Commander, Planner Y.-K. Ko: Commander Command file: 02.01.05.21:33:22.cmd.log 02.01.07.16:36:32.cmd.log Activity: --------- 1) Comet Machholz Background Study Sequence: 02.01_C_Machholz_BG.tcl SCI_SPEC: We will observe Comet Machholz at its perihelion at 0.124 AU. We will derive the outgassing rate from the Ly alpha intensity, the solar wind proton flux from the break point where the Ly alpha intensity drops as H atoms are destroyed by charge transfer, and (we expect) evidence for a comet bow shock from a broad component of Ly alpha. We will also search for O VI emission from charge transfer of O+6 ions with neutrals, O I and N I from photodissociation of evaporated ices, He I, Ne I, Ar I from gas trapped in the comet, and the H_2 and CO bands that have been detected in comet C/2001 A2 (LINEAR) in FUSE observations.
