The reason is a severe drive issue, possibly due to a motor fault. The issue is actively being investigated with top-priority, but until further notice ONSALA60 should only be scheduled as "tag along". This was already communicated to IVS last week, but I thought we should, for completeness, also send an email for this particular experiment. ================================ rv149sh START ================================= 2021-09-08 17:28:43 rv149, sheshan, startmessage Dear colleagues Sheshan Station has started rv149 in mark5b mode and used CDAS as the terminal.
