| Dear GRAS SAF GTS User

Issued 2009-09-18 08:00 UTC

Due to an scheduled outage of GRAS level 1b data no GRAS SAF products were
disseminated between instrument sensing times 2009-09-17 13:51:30 UTC
and 2009-09-18 04:03:43 UTC.

Please see messages from EUMETSAT below.

Dear all,

GRAS - or rather our processing of its data - continues to surprise us.

Contrary to our expectations, the POD recovery after the out-of-plane manoeuvre
earlier today did not take place as smoothly as we hoped it would. We have just
experienced a second (unplanned) reset, which means that the GRAS higher level
data products will not be back to nominal quality before tomorrow morning (our local
time). Correspondingly, we have decided to postpone the start of the dissemination
of GRAS level 1 data until at least then.

We will monitor the further development of the orbit performance and inform you as
soon GRAS data becomes available again.

With kind regards,

 Christian.
