Scientific Category 3. Proposal For 4. Cycle SOLAR SYSTEM,GIANT PL AUG/HRS 4 ------------------------------------------------------------------------------------ 5. Investigators Contact? PI: TRAFTON, LAURENCE UNIVERSITY OF TEXAS AT AUSTIN ------------------------------------------------------------------------------------ 6. Abstract Observe the Ly-alpha profile of two bright northern auroral emission regions on Jupiter to study excitation processes, proton precipitation along field lines, excitation particle flux, and atmospheric properties. A determination of the auroral D/H ratio will be attempted. ------------------------------------------------------------------------------------ Observations Description ------------------------ Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- ------------------------------------------------------------------------------------ Data Distribution Media: 8MM Blocking Factor: 10 Ship To: PI_Address Ship Via: UPS Email: , ------------------------------------------------------------------------------------ 5167( 10) - 12/12/95 12:29 - [ 2] TARGET LIST b)Solar System Targets ------------------------------------------------------------------------------------------------------------------------------------ TARGET NUMBER: 1 | TARGET NAME: IO ------------------------------------------------------------------------------------------------------------------------------------ TARGET DESCRIPTION: SATELLITE IO ------------------------------------------------------------------------------------------------------------------------------------ TARGET POSITION LEVEL 1 | TARGET POSITION LEVEL 2 | STD=JUPITER | STD = IO | ------------------------------------------------------------------------------------------------------------------------------------ TARGET POSITION LEVEL 3 | WINDOWS | | SEP OF EUROPA IO FROM EARTH GT 12", SEP | OF GANYMEDE IO FROM EARTH GT 12", SEP OF | CALLISTO IO FROM EARTH GT 12", WND1 = 10 | -MAR-95 TO 20-APR-95 | ------------------------------------------------------------------------------------------------------------------------------------ DATA | COMMENTS | TYPE=G2V | FOR SATELLITE-ASSISTED ACQUISITION V = 5.0 | OF JOVIAN AURORAE.
