Experts at work trying to set up the sun photometer with the older gear-driven tracking mount	The hammer didn't work. Perhaps bowing in prayer will.	That did the trick! Happy sun photometry!

Instrument Status

1) ARCS2 Site Instruments : WSI being worked on. Decision was made to bypass broken relay. Perhaps it will be running by tomorrow. All individual clocks have been correctly referenced to UTC except the MWR. Awaiting reset procedures from instrument mentor for this.

 

2) Nauru99 Ancillary Instruments : HSI camera has come back to life, but at a degraded level. You can make out the sky, but the image is speckled and streaky. Replacement camera is on it's way. RSR working well. PSU Sun Photometer up and running, tracking well. Needs refinement of north-south alignment. Didn't get to cavity setup today. Top side met towers still functioning at last report. CIMEL appears to be functioning.

 

Commentary : Another day in paradise! Things are ramping up in anticipation of the start of the large triangle phase. We actually managed to participate in the evening 6 PM radio conference, with the kind services of MJ Post on the Ron Brown as relay to the Mirai. We agreed to try a 10 PM session to see if nightfall improved HF communications. Plans were finalized, given the expected arrival of the Ron Brown on station late Wednesday afternoon, for the first Cessna flight to occur on Thursday. We agreed on primary and secondary VHF radio frequencies to use for aircraft communications.
