The wind was boarder line most of the night and seemed to cause some strong power flickers. We had three strong flickers at: 19:40, 00:21, 05:04. The first resulted in the dew point alarm going off and the other two affected the drives, stopping them and I had to execute an axis init but no time was lost. A PR was sent just in case. ----------------- The Story of the International Venus Conference Chapter 2: The Lost One After a successful hike, our little band of trekkers plodded down to the onsen. With nearly an hour until the buses were set to depart, there was plenty of time to relax. I soaked in the water for all of 5 minutes before having my fill of the heat. However, I could either stay in the hot water or leave for the buses and forced to be social. I chose the water. It should be noted that I gauge time poorly. By the time I left the water and collected by watch, I discovered that only 10 minutes remained to make it to the bus. Exiting the building as quickly as possible, I noticed that only my shoes remained on the shoe rack. Surely my friends noticed this when they left. Many people who suffer from social anxiety also suffer from travel anxiety. I regularly have nightmares about being lost in a foreign country, alone, unable to speak the language, armed only with a dead cell phone, a cell phone without service, or no cell phone at all. I tried not to think about those nightmares as I rushed up the hill, terror rising in my throat. I knew even before I reached the designated meeting point that the buses were gone. Everyone was gone. And my cell phone had no service. I was lost somewhere in the mountains of Japan. Who knew I was missing?? Why hadn’t I set up a buddy system?! I hadn’t set up dinner plans with anyone. How long would it take before someone noticed that I was gone? I was set to give my talk tomorrow afternoon, surely at that point someone would realize there was a problem. I had no cell service. I had no flashlight. There was no moon that night. I was 15 miles from the hotel and I didn't know the way back. It really is quite amazing how the ability to reason simply ceases when one enters a state of panic. Basic logic goes out the window. You can actually feel coherent thought becoming throttled and grind to a rusty halt. I was literally becoming stupider by the second. If I did not find a solution soon, I was going to drop into a complete catatonic state of panic. I needed a phone. I passed by the visitors center. It closed an hour ago. The onsen would close in 15 min. I tearfully asked people for help but no one could understand me. Eventually an employee was found and understood I needed a phone but I couldn't communicate that I needed to call the hotel. Finally, a rusty gear clicked back into place. Before leaving for our excursion, we were all handed a slip of paper listing the hotel's phone number. It was in my badge! With shaking hands, I was able to call the hotel. They were sending someone to pick me up. I practically sat in the middle of the road just to make sure I did not miss this bus. 20 minutes later, the conference secretariats pulled up in a beat up white van, it may as well have been a white steed ridden by knights in armor. Fueled with a lifetime of crippling nightmare material and choking back tears, I climbed into the van. They just laughed at me, it seemed I was the least of their worries. With night falling, I was told that 10 people were still missing. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 19:48 dcamera 562( 1289) 91 76 16.1 18.3 18.4 18.1 16.5 -- 1.22 21:39 dcamera 563( 1183) -111 65 16.1 16.1 16.8 15.9 15.9 -- 1.15 00:11 ecamera 536( 213) -21 66 13.9 14.3 15.1 14.2 14.0 clear 0.91 01:55 ecamera 525( 142) -152 75 13.4 13.2 13.9 13.1 13.2 clear 0.83 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 73 28 16 243 (WSW) 391 clear none 17:00 70 25 15 265 (W) 476 clear none 18:00 69 25 24 247 (WSW) 572 clear none 19:00 68 24 17 250 (WSW) 438 clear none 20:00 65 21 20 257 (WSW) 423 clear none 21:00 63 19 21 265 (W) 457 clear none 22:00 62 18 24 264 (W) 392 clear none 23:00 61 18 17 259 (W) 381 clear none 00:00 61 18 21 245 (WSW) 409 clear none 01:00 60 17 21 275 (W) 647 clear none 02:00 60 14 16 275 (W) 622 clear none 03:00 58 15 19 266 (W) 489 clear none 04:00 58 14 20 266 (W) 360 clear none 05:00 57 16 18 263 (W) 311 clear none 06:00 56 21 15 265 (W) 313 clear none Note: the wind was coming from the azimuth listed.
