    • weather about 3-4mm PWV
    • f191a pretest 094-1150 : ok
    • 094-1200 : 2013+370 : adjustment of R2DE clk power level 2.0 dBm to 2.5 dBm just before scan, seems to have distrupted R2DBE so it reports huge clock offset; NOEMA correlator also suffered a hang-up; scan probably not good; re-ranrun start_backend.py and M6_CC after this scan
    • 094-1211 : 2013+370 : started ok : vdiftimeUDP ok, recording ok, power levels slightly high i.e. a bit of clipping, adjusting analog levels down after the scan : relatively good
    • 094-1218 : 2013+370 : ok, powers levels not adjusted yet, local fringes most stable 12:11:40--12:18:10, good
    • 094-1231 : sun avoidance : recorded but no source
    • 094-1237 : sun avoidance : recorded but no source
    • 094-1248 : sun avoidance : recorded but no source
    • 094-1255 : switched to R-Cas SiO : recorded, first 20sec are off-source, rest are ok, local test scan
