N23L12023-03-06Jun YangSuccess, , , , , , , , , , , , , , The new 2L2H DBBC3 backend also participated in the observations. The firmware DDC_E_v126 was used. The frequency setup was set by FS instead of the DBBC3 configuration files. So, the firmware was not re- loaded before the observations. To support the rapid fringe tests with SFXC, we used two 128 MHz filters (RCP: BBC01 USB, Thread 0; LCP: BBC09 USB, Thread 1) and recorded the two-thread VDIF data as a single file for each scan.
EJ027A2023-03-07Jun YangSuccess, , , , , , , , , , , , , , There were some transient (<~15 s) off-source events resulting from high-speed winds and undesired gap/backlash between gears in the old mechanical system. These off-source data will be flagged out when the uvflg file is used.
ES106A2023-02-27Jun YangSuccess, , , , , , , , , , , , , , No known problems.
EO019B2023-02-26Jun YangSuccess, , , , , , , , , , , , , , Noticed many transient (<~15 s) off-source reports. This tracking issue was caused by the undesired backlash in the old mechanical system. These problematic data will be excluded when the uvflg file is used.

GV028A2023-02-25Jun YangMinor failures, , , , WIND, , , , , , , , , , There were a great number of transient (<20s) off-source reports in the FS log file. This tracking issue was caused by high wind pressure and undesired backlash in the old mechanical system. These problematic data will be flagged out during the data reduction when the uvflg file is used.
ES103H2023-02-24Jun YangMinor failures, , , , , , , , , , , , , , There were some undesired transient (<20 s) off-source events resulting from worn out gears in the 70-yr old mechanical system.
ED050B2023-02-24Jun YangMinor failures, , , , WIND, , , , , , , , , , The telescope was stowed during UT 5:29 -- 7:47 because of high- speed winds.

GV028C2023-03-13Jun YangMinor failures, , , , WIND, , , , , , , , , , Missing some scans at the begining (UT 21:30-23:44) because of high-speed winds. There were also some transient (<20 s) off-source events because of worn-out gear teeth in the old mechanical system. These off-source data will be flagged out when the uvflg file is used.
ES106B2023-03-12Jun YangMinor failures, , , , WIND, , , , , , , , , , There were many transient (<20 s) off-source reports because of worn-out gear teeth in the old mechanical system. These data will be flagged out when the uvflg file is used.

EJ027B2023-03-09Jun YangMinor failures, , , , , , , , , , , , , , Off-source during UT 13:05-15:46 because of high-speed winds. There were many transient (<20 s) off-source reports because of worn- out gear teeth in the old mechanical system. These data will be flagged out when the uvflg file is used.
