CHANGES SINCE LAST REPORT.
None.

THIS WEEK'S POSSIBLE EVENTS.
None expected.

NOTES.

1. Three of the older NOAA weather satellites which have been
    decommissioned and are tumbling freely are known to sporadically put
out
    a carrier on 137.500 MHz.  The satellites are TIROS-N, NOAA 6 and NOAA
9
    When the relevant footprints overlap this will cause interference to
    NOAA 15 when active on this frequency.
    Latest report below.
    01/05/09 - Report of consistent interference on NOAA 15 signal when
    NOAA 9 footprint overlaps. My thanks to Steven Ross for this report.

2. NOAA 16's APT transmission system failed a few months after launch.

3. Metop-A's A-side LRPT transmitter has failed.  Currently the redundant
   B-side transmitter is off until further notice (No further service
   expected due to interference with HIRS instrument).

4. NOAA 14 was decommissioned on 23rd May 2007.

5. NOAA 12 was decommissioned on 10th August 2007.

7. Elements are available from :-

    http://www.space-track.org    and
    http://celestrak.com/NORAD/elements/

LAUNCHES.
None due.
Possibility of Okean 5 launch 2009/2010


SECTION 2:   POLAR  HRPT/AHRPT  REPORT -- 17th August 2009
   ==============================================
CHANGES SINCE LAST REPORT.

Metop-A         1701.3       RHCP       AHRPT        Good (note 4)

NOTES.

1.  NOAA 14 was decommissioned on 23rd June 2007.

2.  NOAA 12 was decommissioned on 10th August 2007.

3. On Friday 19th September 2003 NOAA 16 developed AVHRR synch. problems
    similar  to those on NOAA 14 (and previously NOAA 15).
    Since then reports have been mixed.  Some periods of good data, some
    poor.
   UPDATE:  Scan motor performance has recently improved.

4. On 25 May 2009, Eumetsat extended the coverage of the Advanced High
    Resolution Picture Transmission (AHRPT) system on Eumetsat's Metop-A
    polar-orbiting satellite. The improved service provides additional
    coverage over the Gulf of Mexico and Indian Ocean regions.
    For more information, please see:
    http://www.eumetsat.int/Home/Main/Media/Features/710601

5. Feng Yun 3A was declared operational on 12th January 2009.  My thanks
to
   Johnny Lin for drawing this to my attention.
   I am also grateful to Dave Wright of Dartcom for confirming that
   unfortunately (as usual) the Chinese have not strictly complied with
the
   CGMS AHRPT Global Standard so reception using a standard Metop AHRPT
   receiver is not possible.

LAUNCHES.
Meteor M N1 launch tentatively set for 15th September 2009.
