  I decided to send you all a brief summary of the data that were collected 
during those hectic two weeks in early September.  All of the missions were 
accomplished and the imagery is extremely exciting.  Thanks once again to 
everyone who helped.


 SUMMARY OF SPECIAL GOES -9 DATA COLLECTION


  DATE           JD             TIME                       Satellite collected

  3Sep1995  95246-47  1830-1830 UT      GOES-9, Sch. A, 15-min., over Pensicola, FL

     WEATHER - New convection forms along remnants of a north/south-oriented 
land breeze in the central Gulf, and a few weak storms form over southern FL 
on the seabreeze.


  DATE           JD             TIME                       Satellite collected

     WEATHER - Previous day's land breeze in central Gulf of Mexico 
continues to form convection.  Meanwhile, a land breeze south of Cuba merges 
with an island breeze from the Isle of Youth forming new convection over the 
channel.  There is some weak seabreeze convection in south Florida.


  DATE           JD             TIME                       Satellite collected

     WEATHER - Centered over Hurricane Luis (category 4) just after it hits 
Antigua (storm center was about 40 mi NW of island at beginning of 
collection).  There is a lot of gorgeous mesoscale action in and around the 
eye.  24 hours of 1-min collection continues as storm brushes Leeward 
islands.

     WEATHER - 1-min begins with Hurricane Luis as it moves out to sea north 
of Leeward Islands, then goes to 15-min overnight and picks up again at dawn 
with the storm about 250 miles north of Puerto Rico.

On-the-fly plans for GOES-9 test schedule

The most recent items are listed first...


--------------------------------

Date: Fri, 15 Sep 95 09:39:00 PDT

And here we have the final GOES-9 test series forecast . . .

For the period 1800 UTC on 16Sep through 1800 UTC on 17Sep we would like to 
continue with Schedule C, centering over 20N 68W.

Thanks for all your help, and tell all involved that we appreciate their 
efforts in helping to assure that this test series was successful.

--------------------------------

Date: Thu, 14 Sep 95 09:51:00 PDT

As per our phone converstation, we would like to initiate a GOES-8, 1-min 
SRSO schedule beginning tommorrow, 15Sep at 1943 UTC and continuing through 
to 0143 UTC on 16 Sep.  The location will be sector #6, which is centered 
over Puerto Rico.

--------------------------------

Date: Thu, 14 Sep 95 09:36:00 PDT

As per our phone conversation this morning ... For tommorrow's collection 
(which begins at 1800 UTC on 15Sep and goes through 1800 UTC on 16Sep) we 
will continue with Schedule C, but move the senter point to 18N, 65W.

--------------------------------

Date: Wed, 13 Sep 95 09:33:00 PDT

As per our phone conversation, we would like to continue with 
Schedule C for the period 1800 UTC on 14 Sep through 1800 UTC onb 15 Sep. 
The sector center should be changed to 14N, 65W.   My guess is that we'll 
be tracking this storm up through Jamaica for the rest of the test, since 
the mid-latitudes seem to be fairly calm at this point.

--------------------------------

Date: Tue, 12 Sep 95 09:34:00 PDT

First -- as per our phone conversation, tommorrow (i.e., beginning at 
1800UTC on 13 Sep) we would like to run Schedule C, centered at 14N, 58W for 
a potential named storm approaching the Lesser Antilles

Second -- just got a message from Jamie H. suggesting that the special tests 
will be going through Sep 18th.  That means our last forecast will be on Sep 
16th to cover the period 18UT on the 17th through 18UT on the 18th.  Is that 
the correct interpretation? 

--------------------------------

Date: Mon, 11 Sep 95 10:29:00 PDT

Today's collection (which begins at 1800 UTC, 11 Sep and ends tommorrow 
at 1800 UTC on Sep 12) will be schedule C centered at 33 N, 83 W.

The collection which begins tommorrow at 1800 UTC (12 Sep) and ends 1800 
UTC on 13 Sep will be schedule B, centered at 34N, 92W.

--------------------------------

Date: Fri, 08 Sep 95 09:40:00 PDT

Gordon - - sorry about refering to today's start time as 12 UT in 
yesterday's message.  Thanks for catching it.   I, of course, meant 1800 UTC

Now, back to business.  As per our phone conversation this morning, the 
following schedule is set for this weekend.

1800 UTC Saturday (9 Sep) through Sunday 1800 UTC (10 Sep) - - this will be 
schedule C centered at 33N, 70 W for hurricane Luis.

1800 UTC Sunday (10 Sep) through 1200* UTC on Monday (11Sep)  - - schedule F 
which is a 10-min continuous collection over South America using the sector 
that you and Jim predefined.   THEN from 1200 UTC on Monday through 1800 UTC 
we will switch to schedule C centered over 45N and 60 W.  For this six hour 
period, we will switch the soundings from the F sector to the North 
Atlantic.

GUESS - - From 1800 UTC on Monday to 1800 UTC on Tuesday we may want to 
stick to 45N, 60W for the first six hours, then switch to another location. 
We will plan on running schedule C in any case.  More on that Monday 
morning when we see where Luis is located.

--------------------------------

Date: Thu, 07 Sep 95 11:12:00 PDT

The collection which begins tommorrow (8 Sep) at 1200 UTC will be the North 
Atlantic sector.  The schedule will be schedule E, the soundings will be 
done over the prescribed N. Atlantic sounding area, and the 1-min imaging 
will be centered at 45N, 50W.

Tentatively for the weekend it looks like Schedule C over Bermuda beginning 
18 UT on Satuday, Schedule F beginning 18 UT on Sunday, and possibly 
Schedule C or D over the northeastern coast of the U.S. on Monday depending 
on what Luis does.  We will have a final decision by tommorrow morning's 
call regarding the weekend, and particularly Monday.

--------------------------------

Date: Wed, 06 Sep 95 10:09:00 PDT

Gordon -- to confirm the plan for the next 48 hours ...

From 1800 UTC today (6 Sep) till 1800 UTC tommorrow (7Sep) we will be 
running schedule C which will be centered over 20N, 65W.  This is perfect, 
because the eye of hurrican Luis is at that exact location.

Beginning tommorrow we will be switching to schedule B.  Schedule B timing 
will continue throughout the 24 hour period, but the sector center will vary 
as follows:  for the first hour 1800UTC  to 1900 UTC (on 7 Sep) we will 
center the imagery at 60N, 110W.  After one hour we will switch the sector 
center to Washington, D.C. -- roughly 39N, 77W.  Then, for the last hour of 
the 24 -- that is, from 1700 UTC to 1800 UTC (on 8 Sep), we will again 
switch back to 60N, and 110W.

We will talk on the phone tommorrow morning at roughly 11:30 your time 
local, to discuss where the sector goes after that, as well as get a 
preliminary outlook for the weekend.

--------------------------------

Date: Tue, 05 Sep 95 12:08:45 EST
     
     After coordinating with NWS field sites, it's a go for GOES-8 SRSO 
     today, Sept. 5, from 1843 UTC to 2343 UTC; sector six or the Puerto 
     Rico sector will be used.

--------------------------------

Date: Fri, 01 Sep 95 10:22:00 PDT

John P - - We would like to tentatively designate Tuesday, 5 September 1995 
an SRSO special 1-minute collection day.  The sector would be Sector #6, and 
the times would be roughly 1900 UTC through 0100 UTC (6 Sep).  There is a 
fair chance that we will be calling it off early Tuesday morning, but right 
now it looks pretty good.

--------------------------------

Date: Fri, 01 Sep 95 10:03:00 PDT

From Sunday through 1800 UTC on Tuesday, 5 September 1995 we will be running 
schedule A which is the so-called "routine mode".  As I understand it, we do 
not have to supply a sector center for Schedule A.

Beginning on Tuesday, at 1800 UTC, we would like to run schedule D which is 
the "Hurricane near Land".  This schedule allows near continuous 1-minute 
imaging from 1800 UTC on Tuesday to 1800 UTC on Wednesday.  Tentatively we 
would like the sector to be centered at 65W longitude, 20N latitude, with 
the understanding that we can adjust the centering up to 10:00 AM EDT on 
Tuesday morning.
