		UVS/EUV bullets for GEM orbit quicklooks

E12
*Satellites		Europa tenuous atmosphere
			Io atmosphere
   E12 IUSURFAC01 	1304-1319 (wavelength command should be same as in 
			G1 neutral cloud; 16 step?). First 1.5 hours, on 
			body with TMC (11.3 RJ) Second 1.5 hours, on body 
			with TMC, 2-step. Third 1.5 hours, with 16-step cmd, 
			45 min. with TMC at 2 Io radii and 45 min. with TMC 
			at 3 Io radii. We do not need to do a bkg measurement 
			for this wavelength, and we are into almost 10 RJ at 
			this point so we need to spend as much time as 
			possible at each location.

*Magnetosphere		
*Jovian Atmosphere	Upper atmosphere energy budget

E14
*Satellites		Europa tenuous atmosphere and surface composition
			Io atmosphere
   E14 IUSURFAC01	1356-1479 (waveth cmmd should be same as in G2 
			neutral cloud; 16 step?) same positioning as in E12 
			IUSURFAC01, for the same reasons.
 
*Magnetosphere		Io plasma torus energetics
*Jovian Atmosphere	North polar aurora energetics

E15
*Satellites		Europa and Io tenuous atmosphere and surface comp.
   E15 IUATMOS01	full G/G scans for entire 2 hrs with TMC on body at 
			15 RJ. Past full G/G scans on Io in sunlight (G1 
			pre/post eclipse, G2 pre/post eclipse, G1 neutral 
			cloud, E4 pre/post eclipse, E6 post-eclipse) did not
			spend enough time on the body (4-18 rims) and/or were 
			too close in to Jupiter to get a good signal.
 
   E15 IUSURFAC01 	full F/F scans for entire 1 hr with TMC on body at 
			12.6 RJ. To complement other phase/longitude 
			observations.

C21
*Satellites		Callisto and Io surface composition
   C21 IUDARK01		full G/G scans for entire 3.25 hrs in eclipse with 
			TMC on body at ~13 RJ. Previous G/G measurements of 
			Io in eclipse spent a maximum of 18 rims on Io.
