Cleaned the 2DS during preflight. Horizontal element voltages look much better. No noise preflight. Spray test showed up in both H and V. Again, we see particles when detected in both channels but the noise does persist and I believe it all good data can be cleaned up post processing.
No DPR this flight. DPR flashing service mirror. Attempted to blow it out with no success. Not enough time to take it apart and clean.
CDP issue. After power up the laser current went to 90mA for about 20 seconds and down to zero. Laser power monitor voltage spiked to 4.68 for about 2 seconds and dropped to zero. Last flight the current was at 84ma and the voltage was at 2 volts. I suspect that laser is done. We flew at 40000+ feet for about 7 hours at very cold temperatures and then landed in Guam.
Cycled power on VCSEL at 02:37. Appears to have gotten iced over going through some rime. Gone at 02:28. Back at 02:39.
