Subject: WESTPAC


Dear colleagues,
We must inform you, it is very possible that confusion take
place with identification WESTPAC satellite. This satellite was
separated from RESURS satellite together four other minisatellites.
In accordance to NORAD information we thought that WESTPAC is
satellite with ID 1998-043E. Owner of RESURS fulfiled analysis on the
basis of real orbit of RESURS satellite derived from
radiomeasurements, calculated separation pulses of minisatellites and
precise orbit of 043E satellite derived from laser observations and
think that satellite was named in NORAD as WESTPAC (043E) is in
reality Israeli satellite TECHSAT, ID RESURS is 043C and ID WESTPAC
is 043. Returns from TECHSAT we can explain some reflected surface
on this satellite.
If it is so that we can explain strange changes of brightness of
former WESTPAC (ID=3D043E) which SLR station Riga observed 15 July and
peculiarity of laser returns.
Now =ED=F3C sent to SLR community IRVs for 043=E1 satellite on the
basis NORAD TLE and we hope that indification is right. We ask you
to support tracking ”new” WESTPAC ( ID=3D043A) .
