Subject: Outage of CHAMP/GRACE Predictions

Dear colleagues,

as of November 15th, 2003 until November 17th, 2003 an interruption of
the GFZ CHAMP and GRACE predictions occured. The reason was the reception
of corrupted data files for the predictions of solar and geomagnetic
activity from an external institution corrupting our data base. Due to
the missing information no updating of orbit predictions for the CHAMP
and GRACE satellites was possible. As of today November 17th, 2003 our
data bases are resurrected and updated and the prediction cycles returned
to automatic operations, again. In order to prevent any interruption of
this type some more robust software will be applied in future.

We apologize for any inconveniences this may have caused.

Best regards,
R. Schmidt,
R. Koenig

From: Roland Schmidt
