Can't open /dev/rmt/Ombn, No tape or write protected. Cycled power to drive. Tape not loading properly, investigating. CHIP COMMENT: Thu May 15 16:35:27 GMT 1997 Cycled power to Kii. Tape loaded led went on properly. Ejected tape. Cleaned drive with LOWL 18c cleaning cartridge. Reloaded tape. Temperatures low because I forgot that the circulator kicks off whenever there is a power interruption. It was off since yesterday's 2020UT power outage. Reset it.

DPMON COMMENT: Thu May 15 16:54:48 GMT 1997 Exposure or display gains off, or it could be the cirrus, but display looks very underexposed. Cranked it to 8. DPMON COMMENT: Thu May 15 16:56:38 GMT 1997 Megaplus exposure set to 100ms. Red mark (old??) at 500ms. Should be at correct exposure because nothing was touched recently.

WEATHER COMMENT: Thu May 15 17:26:13 GMT 1997 Cirrus is still there, very thin, structure faint. Breeze is very light and coming upslope, northwesterly. Contractors are at work creating their obligatory dust. Danger to objective lenses and instrumentation "iffy" at this time. Due to Rocket launch scheduled for 1900 today, I will keep running, with a certain amount of risk, and monitor the wind and dust closely.
