		PRELIMINARY ARC 3.5M SCHEDULE FOR 2ND QUARTER 1998
			     E. TURNER 3/9/98


			NOTES: ***PLEASE READ***

	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 6 nights.
	No contingent engineering time has been scheduled this quarter.
	Thus, scheduled engineering time will be at approximately the 7%
	level.  Note, however, that one or more extended engineering
	shutdowns may be carried out in order to pursue tasks related to
	the Three Year Plan upgrade efforts.  Such shutdowns will result
	in cancelation of scheduled science programs.  Please see message
	#160 under apo35-general in the email exploder archives maintained
	on the Princeton web site for further information.

	In addition to such 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
	"hot pursuit" of one of the high priority "teething troubles".

	D and G first halves in April and May were in extreme demand and
	were all taken before half of the total time was allocated.  Thus
	a few mid-priority programs could not be scheduled.

				IMPORTANT - OPEN TIME!:
	Eighteen half nights of OPEN time, scattered throughout the quarter
	but starting as early as 5 April, are available; this breaks down as
	11B/3G/4D.  Requests for this time should reach me ASAP but no
	later than March 31.  Requests for this time *must* be passed through
	your institutional scheduler.

	-----
	EN01 = engineering time (Gillespie)
		no science observations scheduled

	-----
	DD01 = Director's Discretionary Time GRB Afterglow Program (UW)

	-----
	JHU Note:  115% of nominal share scheduled.
	-----
	JH01 = 2Q98JH01 Heck S R 
	JH02 = 2Q98JH02 Ford D R
	JH03 = 2Q98JH03 Conn G R
	JH04 = 2Q98JH04 Wyse S R
		April 2nd halves not available at this priority.
	JH05 = 2Q98JH05 Wyse G R
		Note that there is almost no B time in the second half
		of April.  Program time constraints are thus very tight.

	-----
	NMSU Note: 92% of nominal share scheduled.  
	-----
	NM01 = NM01 Harr D R
	NM02 = NM02 Hoop D S
	NM03 = NM03 Hame D S
		Need to specify DIS gratings.  There is no first half D or
		G time in early May, and April first half D and G already
		taken at this priority.  Thus, schedule request could not
		be exactly met.  Please declare scheduled time OPEN asap if
		it is not usable.
	NM04 = NM04 Holt D S
		First choice time not available.  Second choice scheduled.
	NM05 = NM05 Geha S S
		Requested time not available; not scheduled.
	NM06 = NM06 Madd AMBER S
	NM07 = NM07 Marl G S
	NM08 = NM08 John D/G R
	NM09 = NM09 McNa D S
		Need to specify DIS gratings.
	NM10 = NM10 Will G S

	-----
	PU Note: 76% of nominal share scheduled.  Undersubscribed B time.
	-----
	PU01 = 982PU01 Turn D S in April-May; S S in June
		Non-block scheduling.  See note in BLOCK CAPS just before 
		schedule below.
	PU02 = 982PU02 Fan D R
	PU03 = 982PU03 Trem S S
	PU04 = 982PU04 Turn S R

	-----
	UC Note: 108% of nominal share scheduled.
	-----
	UC01 = 251 York S R
	UC02 = 261 York D R
	UC03 = 255 Coor D R in dark time; G R in bright
	UC04 = 254 Kent D S
		One half night is a May 2nd half due to inavailability of
		1st halves at this priority.  Please declare OPEN asap if
		it is not usable.
	UC05 = 258 Kron D R
	UC06 = 260 Coor D R
		Despite being a monitoring program which may have wanted
		time in less than half night blocks, this request gave
		zero detailed scheduling info/constraints.  It is nearly
		impossible for me to guess how the program should be
		scheduled based on nothing more than an object name and
		a general science goal.  Also, note that it is very difficult
		to schedule monitoring programs at low priority.  Although
		it might have been better to leave this program unscheduled,
		I have assigned it time more-or-less arbitrarily when the
		target object is in the sky.  If the assigned time is not
		usable, please declare it OPEN asap.
	UC07 = 262 Kibb GSFC_InB_Cam S**	<----VISITOR INSTRUMENT
	UC08 = 256 Here G R
	UC09 = 257 Turn S R
		Requested time not available; not scheduled.
	UC10 = 252 York D/G 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.  Eight of nine requested dates scheduled.

	-----
	UW Note: 88% of nominal share scheduled.  UW request under by one
	half night?  Please provide a summary/tally of requests broken down 	
	among B, G and R along with individual program info in future quarters,
	as per allotment instructions.
	-----
	UW01 = UW01 Szko D R
	UW02 = UW02 Beck S R
	UW03 = UW03 Dier S R
		Dark time allocated but specified "ideal" schedule includes
		bright and gray time; scheduled as requested.
	UW04 = UW04 Skel D/S R
	UW05 = UW05 Ande S R
	UW06 = UW06 Zuck S/D R
		All scheduled time is dark, rather than half gray, as this
		worked better in the June schedule.
	UW07 = UW07 Wyde S R
		Requested time not available; not scheduled.
	UW08 = UW08 Bali D S
		It is not entirely clear whether the dates listed under
		schedule constraints are the only acceptable ones or the
		only unacceptable ones.  I have assumed the former.  Note
		that about half of the listed period is dark eventhough
		bright time was assigned.  Thus, the scheduling constraint
		is very tight.
	UW09 = UW09 Stub GSFC_FabPer S**		<----VISITOR INSTRUMENT

	-----
	WSU Note: 100% of nominal share scheduled.
	-----
	WS01 = WS01 Seck S R
	WS02 = WSU2 Lutz D R
	
	+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
	+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
	MOST PROGRAMS ARE SCHEDULED IN HALF NIGHT BLOCKS.  THE FIRST HALF OF
	EACH NIGHT EXTENDS FROM EVENING TWILIGHT (SEE CALENDAR DISTRIBUTED
	BY GRETCHEN) UNTIL 0010 MST DURING MST AND UNTIL 0110 DURING MDT.

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

	THIS QUARTER TWO DIFFERENT PROGRAMS USE NON-BLOCK SCHEDULING.
	THESE PROGRAMS ARE INDICATED IN PARENTHESES () ON THE SCHEDULE
	AND THEIR TIME ALLOTMENTS ARE LISTED HERE:
	PU01 = 40 MIN EACH TIME IT IS SCHEDULED.
	UC10 = 90 MIN IN 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.
