Please see the message from EUMETSAT below.

Dear all,
 
unfortunately we have to report an outage in the GRAS processing. The instrument started to track an unhealthy satellite (GPS SV 26) at approx 00:04 UTC ; this caused its navigation solution to diverge being unable of producing any valid data since then. The instrument was reset at approx 04:40 UTC, and is back to its nominal status now.

 All disseminated data during the period was flagged as degraded due to a POD reset. In fact the data will be flagged degraded until approx sensing times of 16:00 UTC.

We apologize for the inconvenience this might cause on your side.

Kind regards,

Yago Andres
