Attending: Tanner, Daniel, Vuk

1) Homestake status (Tanner, Gary, Daniel)
status of stations, data flow: Much progress was made during the last visit to Homestake (Tanner, Victor, Pat, Daniel, Vuk). Currently have 18 fully operational stations: 300, 800, five at 2000, three at 4100, four at 4850, and 4 surface stations. Another station is set up at 1700 level, but its network/GPS is not fully working yet. All underground stations have been oriented with Octans during the last trip (the 300 and 800 stations were oriented in the past). The data is flowing from all stations via UMN. Tanner: there was a hiccup in the data flow last week. We have a virtual machine at UMN for antelope, but somehow antelope was shut off (not sure why) and we lost several hours of data. Restarted it, but even though the data was still in the buffer at Homestake, it was not pushed to UMN, so scp-ed it explicitly. But this was not propagated to Caltech and Indiana. Tanner will contact admins at UMN about this. Daniel confirms that the data drop occurred at Caltech too, can scp the missed data over. Tanner: probably not necessary to set up rsync, this happened only once in several months. Vuk: also should be able to catch this with data quality monitoring. Also should check what happens during the move due to Tate building remodeling.
Tanner: 2000-E station is not behaving well
2) Planning next visit: end of May, early June
3) Data analysis:
