    Preflight

    A2D Autocal, no evidence of channel shifting, A2D sn1706 ch 2-6 have shifts in y-int greater than 10mV, none greater than 100mV.

    DPR service mirror light blinking, rebalance on, cycled power then used rebalance x3, still stuck in rebalance

    VXCEL reboot

    RWO dsm came up fine this time, turned probe on before DSM

    Cycled power LWO dsm multiple times, called SE, informed lead tech who informed PI, decision made to fly anyway. Affected instruments are CDP and 2dc-10um


    13:28Z    Wheels up, will try rebalance then power cycle to DPR in dryer, low pressure air

    13:38Z    DPR is back, numbers in family with DPL and VXCEL. LWO dsm still out. Camera on status page is ed but seeing images, will take no action

    13:40Z    Camera web page shows error, cycle stop/start, camera status page green, seeing images advance

    13:58Z    DP_VXL nan, other vars present, serial data dsm MPDB present, cycle power, DP_VXL came back

    14:39Z    after multiple power cycles gave up on LWO dsm, pulled breaker to probes to limit hours on instrument. Left AI breakers engaged.

    16:08Z    AC server is up, dsm server and everything downstream is down, cisco web page shows all ports with a red arrow down. Called SE and lead tech, conference by chat. Restart Nimbus, no help. Restart Nimbus by terminal window command, no help. Restart data acquisition, no help. Restart data acquisition as RF07, no help. Restart ADS computer, no help. Restart router, problem solved. Lost about 1 hr of data, Dropsondes and radar store data locally. Checked dsms and instruments, condition same as start of mission. Note: aircraft experience lightning strike of nose RF05, no burn marks or pitting noted.
