Position: 88 54' N, 177 22' E, temperature - 23 C, air pressure 1017 hPa, wind 7 knots from N. Ice drift 0.1 knot towards N. Shooting seismic continuously. A horrible 50 Hz noise signal appeared, and the source was most likely the generator which we need on continuously. We grounded the lines at both ends and the problem disappeared. Audun restored continuous power for charging the battery of the radiation flux measurements. The power had been interrupted when we moved out of the ice hangar. Cleared rime and snow from the weather station. At the radiation flux site, the sun time detector was covered with rime and the IR detector with snow while the radiation detectors were fine.
