Date: Thu, 11 Jan 1996 14:26:47 +0500 From: email@example.com (Gary K. Davis) For you GOES-7 enthusiasts GOES-7 took what might be its last image at 1331z on January 11, 1996. It was launched on February 26,1987 and went operational on March 25,1987 at 75¡W. It was moved to 108¡W February 1989 as "GOES Prime" a one-GOES system following the January 1989 failure of GOES-6. It was then moved to 98¡ in July 1989 for hurricane season. It was moved back to 108¡ in November 1989 for the Pacific storm season. It was moved back in 98¡ July 1990, then to 108¡ November 1990, back to 98¡ July 91, to 112¡in April 1992 when Meteosat-3 was brought to 75¡ and finally to 135¡ in January 1995 following the commissioning of GOES-8. The spacecraft was operational for over 8 years 9.5 months We took 61,937 full disks 137,794 partial disks 1,147 special storm scans Toatal images 200,878 Total soundingss 77,504 Total scans 278,382 It was truly the GOES workhouse and to all who made it happen congratulations.
Subject: IMPORTANT: GOES-7 SHUT DOWN! From: firstname.lastname@example.org (Jamie Hawkins) Date: Wed, 10 Jan 1996 13:44:27 +0500 IMPORTANT NOTICE: All operations from NOAA's nine-year old GOES-7 satellite will end Thursday January 11, 1996 at 14:00GMT. The last image will begin at 13:30GMT. NOAA has used many avenues to spread this message for several months and hopes that all GOES-7 direct readout users have had the opportunity to recongiure systems for the new GOES-9 spacecraft. GOES-9 is drifting westward past 125 degrees West at 0.93 degrees per day. GOES-9 will arrive at its operational station on January 22nd. Imaging operations continue during the move, with image motion compensation (IMC) off. The government furlough (and the blizzard) have kept many NOAA employees away from their desks for nearly three weeks, but the computer operators and analysts, satellite operators, engineers, programmers and other dedicated personnel of NOAA's National Environmental Satellite, Data, and Information Service have kept this crucial effort on track, with the promise of providing unprecedented satellite surveillence of the Pacific region. Hats off to these remarkable civil servants (who still haven't gotten a full pay check...) who are among the many that will go unnoticed or underappreciated by most of the public. Any GOES-West users running into trouble acquiring or processing GOES-9 data may contact me at the email address above, or via phone (beginning January 11th) at 301-457-5125. ....................................

Subject: TRANSFER OF GOES-7 OPERATIONS TO GOES-9 From: "Soracco, Michael"
Date: Thu, 04 Jan 96 16:16:34 EST GOES-9, planned to replace GOES-7 at 135 degrees West, is currently moving to the west at 0.93 degrees per day. As of today, January 4, 1996, GOES-9 is located near 118 degrees West. It is scheduled to arrive at its new GOES-West station on or near January 22, 1996. IMPORTANT! -- PLEASE BE ADVISED THAT AS GOES-9 APPROACHES GOES-7, ALL OPERATIONS INCLUDING IMAGING AND SOUNDING FUNCTIONS WILL BE TURNED OVER FROM GOES-7 TO GOES-9 ON JANUARY 11, 1996. GOES-9 will be near 125 degrees West on the 11th. The last multispectral image transmitted by the GOES-7 VAS will be at 1331 UTC. The 1348 UTC GOES-7 dwell sounding will be canceled. At 1400 UTC, exclusive GOES-9 imager and sounder data transmissions will commence. GOES-West WEFAX products and DCS operations will also transfer to GOES-9 near 1400 UTC. The final GOES-7 GOES-Tap product reflecting a data time of 1330 UTC will be disseminated at 1400 UTC. The first operational GOES-9 GOES-Tap product reflecting a data time of 1400 UTC will be disseminated at 1415 UTC. A specialized schedule on GOES-9 consisting primarily of full disk image transmissions is currently being used to test and evaluate software recently uploaded to correct several navigation errors. On January 10, 1996, at 1200 UTC, the routine scanning mode will resume on GOES-9 for both imager and sounder. The routine schedule for the imager provides 3-hourly full disk data starting at 0000 UTC, and at other times, three sectors at half-hourly intervals covering the Northern Hemisphere, CONUS and Southern Hemisphere. The routine sounder schedule is broken down into two sectors termed ASOS-1 and ASOS-2, covering the CONUS and adjacent Pacific Ocean. The following schedule based on a reference longitude position of 135 degrees West will be used: Imager Sounder routine at ASOS-1 ASOS-2 HH00/HH30 at HH01 at HH23 Other activities: January 16, 1996, at 2145 UTC --Implement 135 degrees West grid/map data base Prior to the new grid data base implementation date, users should expect a decrease of grid coverage in the west. IMC has been turned "off" thus far to minimize the magnitude of navigational shifts in the data as the spacecraft moves. IMC will be restored following the stop maneuver at 135 degrees West, on or near January 22. An update on GOES-9 operations will be provided prior to the stop maneuver.

Subject: GOES-7 SHUT DOWN! From: firstname.lastname@example.org (Jamie Hawkins) Date: Mon, 18 Dec 1995 10:46:24 +0500 IMPORTANT REMINDER: GOES-7 imaging will be terminated on January 11, 1996. All GOES-West operations will be transitioned to GOES-9. GOES-9 is now moving toward 135W, and will arrive on January 22nd. ALL GOES-WEST DIGITAL DIRECT READOUT USERS SHOULD BE PREPARED TO ACQUIRE GVAR ONLY BY JANUARY 11th!
