		PRELIMINARY ARC 3.5M SCHEDULE FOR 4TH QUARTER 1998
			     E. TURNER 9/29/98


			NOTES: ***PLEASE READ***

	I apologize for the extremely late appearance of the 4Q schedule
	and any inconvenience it may cause.

	The only change affecting the Oct. 1-12 period covered by the 
	partial schedule issued last week is the addition of the UC09
	twilight program on 10/2.

	Except in cases where strong science drivers dictate otherwise
	(a minority of cases), observing time has again been scheduled
	in half night blocks.  
	
	Scheduled engineering time for this quarter amounts to 19 half nights.
	No contingent engineering time has been scheduled this quarter.
	Thus, scheduled engineering time will be at approximately the 10%
	level.

	NOTE HOWEVER that an engineering shutdown may be declared with
	approximately 2 weeks advanced notice to allow installation of
	the new Echelle spectrograph.  This could occur as early as the
	bright run in the beginning of November if preparations go well
	and rapidly.

	In addition to scheduled engineering time, science observations
	may be pre-empted, sometimes on short notice, for urgent
	engineering tasks.  Such tasks include both work that is required
	to safeguard observatory personnel or facilities and that allows
	significant progress on Three Year Plan improvement projects (see
	message #160 under apo35-general for details).

				IMPORTANT - OPEN TIME:
	There are a total of 18 half nights of OPEN time available in
	this schedule.  The majority are bright second halves in November
	and December, but there is even some prime dark time in December
	available.  Requests for this time should reach me ASAP but no
	later than October 31.  Requests for this time *must* be passed through
	your institutional scheduler.

	-----
	EN Note: No science observations scheduled during EN time.
	-----
	EN01 = Periodic engineering time (Gillespie)
	EN02 = Maintenance shutdown (Gillespie)

	-----
	DD Note: Director's Discretionary Time (4%)
	-----
	DD01 = 984DD01 UWGRB S R
		Time will be allocated to compensate programs pre-empted
		by GRB chases.  Data available to all interested parties
		within ARC.  
	DD02 = 984DD02 Lamb D R (low, high) 
		Only one of two requested half nights allocated because the 
		target is too faint (21.7) to allow study of the Ly-alpha
		forest with DIS.

	-----
	JHU Note:  100% of nominal share scheduled. 
	-----
	JH01 = 4Q98JH01 Weav AOTF O
		These observations involve the use of visitor instruments.
		The time is scheduled CONTINGENT upon the PI obtaining
		Bruce Gillespie's EXPLICIT agreement that all the technical
		and logistical arrangements involving the instrument are
		satisfactory AT LEAST 10 DAYS PRIOR TO THE SCHEDULED
		OBSERVATIONS.
	JH02.G = 4Q98JH02 Wyse G O
	JH02.S = 4Q98JH02 Wyse S O
	JH03 = 4Q98JH03 Ford D R (high)
		Only G time available within the constraints at this
		priority.  Please declare OPEN ASAP if scheduled time
		is not usable.

	-----
	NMSU Note: 100% of nominal share scheduled.  
	-----
	NM01 = NM01 Bran S O
	NM02.S = NM02 Rizz S O
	NM02.D = NM02 Rizz D O (low, medium)
	NM03 = NM03 Hoop D O (medium, high)
	NM04 = NM04 King D O (high)
	NM05 = NM05 Harr D R
	NM06 = NM06 Harr G R
		October first halves not available at this priority.  Early
		November scheduled.  Please declare OPEN ASAP if scheduled
		time is not usable.
	NM07 = NM07 Mill D O (low, medium)
	NM08 = NM08 Hame D O (gratings??)
		Please specify desired DIS gratings on scheduling form.
	NM09 = NM09 Deve G O
		October first halves not available at this priority.  Early 
		November scheduled.  Please declare OPEN ASAP if scheduled 
		time is not usable.
	NM10.D = NM10 John D R (high)
	NM10.G = NM10 John G R
	NM11 = NM11 Holt S R
		"Preferred" time not available at this priority.  December
		second halves scheduled.  Please declare OPEN ASAP if 
		scheduled time is not usable.

	-----
	PU Note: 88% of nominal share scheduled.  Undersubscribed B time.
	-----
	PU01 = 984PU01 Turn S O
		Non-block scheduling.  See note in BLOCK CAPS just before 
		schedule below.
		[NOT THE CURRENT VERSION OF THE REQUEST TEMPLATE; SEE 
		APO35-GENERAL MESSAGE #289]
	PU02 = 984PU02 Stra D R (low, high)
	PU03 = 984PU03 Trem S R

	-----
	UC Note: 100% of nominal share scheduled.
	-----
	UC01 = 272 York D R (medium)
		Grey time does not come in whole night blocks; if moon
		phase is <= 50%, then the moon is set for >=50% of the
		night.
	UC02 = 270 York D R (any)
		The discussion of observing schedule constraints in this
		request could be read as implying non-block scheduling,
		but it is not very clear and since half nights are also
		explicitly mentioned, this is what has been scheduled.
		Also, OS participation in data acquisition and/or reduction
		must be arranged and agreed on by all concerned well in
		advance; it cannot be simply welcomed/requested/assumed
		in the proposal.
		[NOT THE CURRENT VERSION OF THE REQUEST TEMPLATE; SEE
		APO35-GENERAL MESSAGE #289]
	UC03 = 277 Lamb D R (gratings??)
		Please specify desired DIS gratings on scheduling form.
		No preference for first or second half of night indicated.
	UC04 = 271 Burl D O (medium, high)
	UC05 = 273 York D R (low, medium)
	UC06 = 278 Harp G R
	UC07 = 269 Here G R
	UC08 = 268 Kron D R (low or medium)
	UC09 = 276 York G/D/S R
		Adler Planetarium twilight program (not accounted to UC).
		Use instrument mounted for the night's first program.
                Non-block scheduling.  See note in BLOCK CAPS just before
                schedule below.  All requested dates scheduled.

	-----
	UW Note: 84% of nominal share scheduled.  Note that several of the
	lower priority programs had strongly constrained and complex
	requests; it is unlikely that such programs can be scheduled when
	there are only scattered holes left to fill in the schedule.
	-----
	UW01 = UW01 Szko D R (high)
		TAC allocated 4 B half nights but the scientific constraints
		of coordinating with spacecraft observation of the targets
		requires assignment of 1 B, 2 G and 1 D half nights.  The
		latter has been scheduled due to the high priority of the
		program, but this throws the overall UW request out of
		B/G/D balance.
	UW02 = UW02 Dier S R
	UW03 = UW03 Dalc G R
	UW04 = UW04 Ande S R
	UW05 = UW05 Rodg G&D R (high)
		Note that *requiring* full half nights means that the program
		will not be scheduled if some higher priority program needs
		a small piece of the requested half night(s)...not a problem
		this time but could be in the future.
	UW06 = UW06 Wyde S R
	UW07 = UW07 Zuck S&D R (low, high)
		No indications of which nights to schedule SPIcam vs. DIS.
	UW08 = UW08 Magn S R
	UW09 = UW09 Toma S R
		Only one of four allocated half nights scheduled.  Others not
		available at this priority.  Note that only 10/11-16 and
		10/23-27 include grey time, not the whole 10/5-27 interval
		as per request.
	UW10 = UW10 Wyde S R
	UW11 = UW11 Kris D ? (medium, high)
		It is not clear whether observations are to be carried out
		remotely or on-site.
	UW12 = UW12 Szko G R
		NOT SCHEDULED.  Constraints far too restrictive to allow
		scheduling at this priority.  In any case, there are never
		full nights of grey time (see UC01 note)!
	UW13 = UW13 Szko D O/R (high)
		NOT SCHEDULED.  Constraints far too restrictive to allow
		scheduling at this priority.  Actually, I don't think it
		was schedulable, but I am not sure I understood the request
		clearly; it was a bit confusing.
	UW14 = UW14 Marg D R (low)
		NOT SCHEDULED.  First halves in high demand throughout the
		quarter and no longer available at this priority.

	-----
	WSU Note: 100% of nominal share scheduled.
	-----
	WS01 = WS01 Lutz D R (low, medium)
	WS02 = WS02 Aust D R? (low, medium)
	
	+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
	+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
	MOST PROGRAMS ARE SCHEDULED IN HALF NIGHT BLOCKS.  THE FIRST HALF OF
	EACH NIGHT EXTENDS FROM EVENING TWILIGHT (SEE CALENDAR DISTRIBUTED
	BY GRETCHEN) UNTIL 0110 MDT or 0010 MST.

	FIRST HALF IS INDICATED BELOW AS "A"; THE SECOND HALF THEN 
	EXTENDS UNTIL MORNING TWILIGHT AND IS INDICATED BELOW AS "B".

	DURING THIS PARTIAL QUARTER 2 PROGRAMS USE NON-BLOCK SCHEDULING.
	THESE PROGRAMS ARE INDICATED IN PARENTHESES () ON THE SCHEDULE
	AND THEIR TIME ALLOTMENTS ARE LISTED HERE:
	PU01 = 50 MIN EACH TIME IT IS SCHEDULED.
	UC09 = 90 MIN PRECEEDING EVENING TWILIGHT EACH TIME IT IS SCHEDULED.

	INSTRUMENT CHANGE TIMES ARE NOT INCLUDED BELOW BUT WILL BE INDICATED
	IN THE SCHEDULE ISSUED FROM APO BY GRETCHEN AND WILL BE SHARED
	BETWEEN ADJOINING PROGRAMS AS USUAL.
