| Author: | Thomas Schildknecht | |
| Content: | Author: Thomas Schildknecht Dear Colleagues, On Oct. 23 some maintenance work on the main power distribution of the observatory resulted in an unnoticed failure of the mains supply to the 24V UPS of our central station clock system which includes several quartz oscillators, the time distribution system and the GNSS timing receiver. Fortunately the H-Maser was not affected. The range measurements are thus not concerned but the station epochs were temporarily wrong by up to 0.1ms. The main station clock systems are currently still not completely stable.
