| Subject: | TWP/MMCR/C3 - MMCR Inoperative |
| DataStreams: | twpmmcrmomentsC3.00, twpmmcrmonC3.00, twpmmcrcalC3.00, twpmmcrpowC3.00, twpmmcrpowC3.a1,

| Description: | During this period, the MMCR at Darwin was cannibalized routinely to keep the Manus and
Nauru MMCRs operational. The largest downtime during this period was due to the
replacement and repair of the antenna. During attempts to "rebuild" the MMCR, data files may have
been generated that are of no use. |
| Suggestions: | Do not use any of the MMCR data during this period. |
