Due to the very late date at which the 1Q1997 schedule is appearing,
I am posting it here as well as distributing it by normal channels
through the institutional schedulers.

		PRELIMINARY ARC 3.5M SCHEDULE FOR 1ST QUARTER 1997
			     E. TURNER 12/23/96


			NOTES: ***PLEASE READ***

	Except in cases where strong science drivers dictate otherwise
	(a small minority of cases), observing time has again been
	scheduled in half night blocks.  

	Scheduled engineering time for this quarter amounts to 13 nights;
	this includes both the 10 nights announced in the allotment email
	plus a further 3 night extension of the December 1996 shutdown
	into January 1997.  It includes one four night shutdown in late
	January for work on the new guider and primary support system.
	No contingent engineering time has been scheduled this quarter.
	Thus, scheduled engineering time will be at approximately the 14%
	level, compared to about 25% in 4Q1996 and 21% in 3Q1996.

	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 personel or facilities and that allows
	"hot pursuit" of one of the high priority "teething troubles".

	The very high priority being accorded engineering work on the
	telescope is NOT permanent policy, but rather a temporary measure
	intended to accelerate improvement of telescope performance.

	There are 3 half nights of OPEN bright time available in March.
	Requests for this time should be sent to me ASAP.

	IMPORTANT NOTE: The tendancy to try to catch setting objects  by
	requesting first half nights early in the quarter was stronger than
	ever this time, and many high priority programs requested large
	blocks of such time.  As a result, all such time was allocated by
	scheduling of roughly the highest 50% of proposals (by priority).
	Thus, many lower ranked proposals could not be assigned the time
	they requested.  In some cases, I have therefore not scheduled
	such programs; in other cases, I have scheduled time that is
	outside the indicated dates if it appeared possible to me that the
	time would still be of some use to the project.  It depended on
	how much information was provided in the proposal.  In some cases,
	it is likely that the scheduled time will not be usable; such time
	can be relinquished and declared OPEN.  Please do this ASAP so that
	we can find the best use for the time.

	Also, restrictions on scheduling based on non-astronomical factors
	(attendance at meetings, ski trips, etc.) were also more common
	than normal in this quarter's requests.  Note that I interpret these
	restrictions literally.  For example, one project gave up the last
	two remaining half nights of dark time in the quarter because the
	observer indicated that he/she was unavailable before Jan. 16.  If
	you intend such non-astronomical dates restrictions as only 
	preferences, not binding constraints, it should be clearly so
	indicated in the request (under "Special Requirements").

	JHU Note:  131% of nominal share scheduled.

	JH01 = 1QJH01 Wyse G R 
	JH02 = 1QJH02 Chan D R
	JH03 = 1QJH03 Heck D R
	JH04 = 1QJH04 Oege D R
	JH05 = 1QJH05 Spaa D R

	-----
	NMSU Note: 88% of nominal share scheduled.  Note that the NM##
	program designations that appear on the schedule correspond to
	the priority ranked NM programs, not the internal NMSU program
	designations even though both have the same format.  In other
	words, NM01 on the schedule is the highest ranked NMSU program
	which is called NM09 in the internal system.  This is a very
	confusing nomenclature and might be better avoided in the
	future.  Scheduler, please make sure your PIs are straight on
	which program is theirs!  Undersubscribed B time
	-----
	NM01 = NM09 Rizz D S
		The listed acceptable dates for this program appear to
		be far more tightly constrained than actually justified
		by the target coordiantes.  Due to the program's high
		rank it was possible to meet these constraints, but please
		do not make the scheduling problem harder than it already
		is by making scheduling constraints tighter than necessary.
	NM02 = NM10 Wats G R
		Only 4 of the 7 allocated half nights were scheduled due to
		the extremely severe scheduling constraints.  Most of the
		time in the dates listed as acceptable is dark and thus not
		available since bright time was allocated to the project.
	NM03 = NM07 Ledl D S
	NM04 = NM01 Carl D S
	NM05 = NM06 Ledl D S
	NM06 = NM04 Hame D S
	NM07 = NM05 Hoop D S
		Grey time allocated; it does not come in full night blocks
		due to mechanics of lunar phases, etc.
	NM08 = NM08 Harr G R
		Requested time not available at this priority.  Second halves
		of January nights scheduled in case they might still be
		useful.  Please declare OPEN ASAP if not.
	NM09 = NM02 Deve G R
		Requested time not available at this priority.  Second halves
		of February nights scheduled in case they might still be
		useful.  Please declare OPEN ASAP if not.
	NM10 = NM03 Geha D S

	-----
	PU Note: 77% of nominal share scheduled.  Undersubscribed B time.
	-----
	PU01 = 971PU01 Turn D S
		Non-block scheduling.  See note in BLOCK CAPS just before 
		schedule below.
	PU02 = 971PU02 Stra F S
	PU03 = 971PU03 Fan  D R

	-----
	UC Note: 111% of nominal share scheduled.

	UC01 = 199 Lamb D R
	UC02 = 195 Hild G R
	UC03 = 191 York F S
	UC04 = 193 York D R

	UC10 = 194 Kron D R
	UC11 = 189 Raus G S
	UC12 = 204 Turn D R
	UC13 = 202 Anni F R
		Although dark nights allocated and make sense given the
		program; the requests specifies preference for dates in the
		bright of the moon!  Since no dark time was available anyway
		at this priority; bright time on the indicated dates was
		scheduled.  Please declare it OPEN ASAP if it is not usable,
		and please proof read proposals more carefully in the future.
	UC14 = 205 Turn G R
		The text of this proposal was not provided although 2 B nights
		were allocated to it in the summary FAX.  I have therefore
		*GUESSED* that it might be a G R request and assumed that
		the targets are the same as for the UC12 program by the same
		PI.  Please provide corrected info as needed.
	UC15 = 188 York D/G R
		Adler Planetarium twilight program (not accounted to UC).
		Some requested nights not scheduled due to engineering
		time or research program requirements for twilight time.
		Eight sessions scheduled.  Use instrument mounted for the
		night's first program.

	-----
	UW Note: 98% of nominal share scheduled.  
	-----
	UW01 = UW01 Rodg G R
	UW02 = UW02 Toma S R
		Need for first half night assumed, though not specified.
	UW03 = UW03 Beck S R
	UW04 = UW04 Dier S R
	UW05 = UW05 Szko D R
		Please supply acceptable dates, not object coordinates
		as per template instructions.  This request is here repeated
		for the second time; it saves me lots of time not to have to
		do mental conversions from RA-DEC to acceptable dates in my
		head for each program.
	UW06 = UW06 Ande D/G/S/F R
		Please specifiy instrument as far in advance of run as 
		possible.  Inform APO staff.
	UW07 = UW07 Stad D S
		Dark time not available during requested dates; grey scheduled
		instead.
	UW08 = UW08 Marg G R
		Please supply acceptable dates, not object coordinates
		as per template instructions.
	UW09 = UW09 Magn D R (1/11-14) G R (1/29)
		Bright time scheduled in second half of night in case it
		is still useful.  Declare OPEN ASAP if not.  First scheduled
		grey night marginally violates special condition, but no
		other such time available.  Again, declare OPEN ASAP if it is
		not useable.
	UW10 = UW10 Marg D R
		Best available time scheduled at this priority.  Declare OPEN
		ASAP if it is not useful.
	UW11 = UW11 Bohm G S
		Dates specified as "best" are mostly not B time.
	UW12 = UW12 Bali S R
	UW13 = UW13 Stub G R
		Time requested not available at this priority.  Not scheduled.
	UW14 = UW14 Stub G R
		Time requested not available at this priority.  Not scheduled.

	WSU Note: 100% of nominal share scheduled.

	WS01 = WSU1 Seck F R
	WS02 = WSU2 Lutz G 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
	AND IS INDICATED BELOW AS "A"; THE SECOND HALF THEN EXTENDS
	UNTIL MORNING TWILIGHT AND IS INDICATED BELOW AS "B".
	IF NO "A" AND "B" ARE INDICATED, THE LISTED PROGRAM
	HAS THE WHOLE NIGHT FROM TWILIGHT TO TWILIGHT.

	THE MONITORING PROGRAM PU01 IS ASSIGNED 45 MIN AT EITHER THE
	BEGINNING OR END OF AN A OR B BLOCK AND IS INDICATED AS FOLLOWS:
	XXXX/PU01 MEANS IT IS ASSIGNED THE LAST 45 MIN OF THE BLOCK OF WHICH
	PROGRAM XXXX HAS THE REMAINDER; PU01/XXXX MEANS IT IS ASSIGNED
	THE FIRST 45 MIN OF THE BLOCK AND XXXX HAS THE REST.

	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.

	PROGRAMS ASSIGNED TO "EVE TWI" SHOULD BEGIN 90 MIN BEFORE THE
	BEGINNING OF EVENING ASTRONOMICAL TWILIGHT AND END AT ITS START.

          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.
 
        **These observations are scheduled for twilight hours and
           are CONTINGENT upon the PI obtaining the EXPLICIT 
           agreement 1) of Bruce Gillespie that site staff can
           accommodate the twilight usage and 2) of the nightime
           observers scheduled for that evening that there will be
           no serious adverse effect on their programs.
