Subject: | TWP/MMCR/C2 - Instrument problem, Degraded hardware |
DataStreams: | twpmmcrcalC2.a1, twpmmcrmonC2.a1, twpmmcrpowC2.a1, twpmmcrmomentsC2.a1

Description: | The radar is down due to IEEE-488 bus problems.
There are sometimes several hours of data available in a given day during this period
(immediately after a system reboot) but the large majority of the data are missing. |
