All scans of OHG116 were recorded by using K5 system with the removable HDDs. The recorded data will be shipped by ice-breaker Shirase and be delivered to Japan in the middle of April, 2019. Our K5 system was synchronized with GPS before starting this session. The clock offset of K5 from GPS is probably less than 0.3937 micro seconds (-0.3937 to -0.2741 micro second). Weather (18:00 UT, 15 Nov.): Sky Conditions: Cloudy, Temp.:-7.3, R.Hum.:86%, Press.:982.7 hPa.
