<p class="MsoNormal">Dear Colleagues,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">There was a failure in the combination of the EOP ultra-rapid product for GPS Week 1924, Day of week 5 hour 12 (igu1945_12). No IGS combined ultra-rapid products was submitted to any of the data centres.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The ultra-rapid orbit combination completed successfully, but the failure in the EOP combination prevented any of the ultra-rapid products from being submitted.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The problem in the EOP combination arose due to an error in matching an epoch date from the UT1. table before the program attempted to apply a tidal correction to the y-rate values. We are still investigating why this occurred.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Regards,<o:p></o:p></p>
