[ROLSS] Safe mode on Meteosat-8

[Nicolas Clerbaux]

Dear GERB data user,

There was a problem with the Meteosat-8 satellite (MSG1) this week-end and the 
satellite is currently in safe-mode (see EUMETSAT message hereafter). The 
imagery service (SEVIRI) is currently performed with the Meteosat-9.  

As the GERB instrument on Meteosat-9 is currently also in safe-mode (eclipse 
season), no geostationary broadband observations of the earth radiation 
budget is currently performed!

We will let you know when the near real time GERB data dissemination will 
resume.

Nicolas

Dear colleagues

At 14:07 UTC (16:07 Darmstadt time) today 23 sep 2006, Meteosat-8 went
into safe mode. No special operations were ongoing and prior to the safe
mode no problems were observed.

Following the safe mode, all operational services have been configured
for Meteosat-9. The necessary configuration changes were implemented at
1800 UTC - configuration of the monitoring tools allowing the
confirmation that the changes had been succesful at around 1830.

DCP acquisition via MSG-2 was activated at around 1700 UTC.

Investigation of the cause of the Meteosat-8 safe mode triggering is
continuing. The main priority today was to confirm that the spacecraft
configuration is ok for eclipse (as we are at the equinox today, the
eclipse tonight is one of the deepest) - the thermal configuration was
checked and ok.

In brief, Meteosat-9 data now appears where Meteosat-8 was. The Met-9
'commissioning' stream has therefore been stopped on EUMETCast.

best regards,


Mikael Rattenborg,
