Homestake Meeting Minutes, 02/19/15
Attending: Daniel, Vuk, Tanner, Gary, Jan, Pat, Victor
Homestake wiki: https://zzz.physics.umn.edu/groups/homestake/home
Our agenda:
1) Homestake status
stations duty cycle: Tanner checked occasionally the data flow, looks like all of the data is coming in except the WTP. Last week centered all seismometers.
data flow: From Homestake to UMN. Tanner emailed the admins to allow access to Caltech and Indiana, didn't hear back. Tanner will go talk to them to speed this up.
frames: Tanner putting together the code for writing frames, much of it ready. In the process will try to do some quick checks of the data quality channels, such as the clock quality, voltage, mass positions etc. Will try to condense all of this information into one number that will specify the state of the given station. Will talk to Gary about which quality channels are important and how to best check/track them.
2) Planning next visit: Mar 23-Apr 3
batteries: Vuk should buy diodes and connectors for Terry to put together the diode boxes. Connectors should make connecting/disconnecting simpler and without additional tools. Should try to do this next week.
Gary will try to send 20 batteries from another project which is finishing. Will be starting to pull them out on March 16, so can get the batteries out by March 19 or 20. Vuk should order 20 batteries for the 4850, and we could use these for the 2000 location.

Pat will rent a car on Friday Mar 20 (should be around 3pm in Lead). Victor will rent another car on Sunday Mar 22 (leaving on Wed). No access days are Mar 27 and 30. Pat might be able to start huddle tests before weekends, we should talk to SURF.
Goals:
Build and install the 4850 station near 17 ledge, including huts and the battery pad (if necessary).
Install the two 2000ft stations. Power and network should be available by the time we arrive (network is currently down).
Install the 1700 station nearest to Yates. Will not have network.
Potentially install another station at 2000, further northwest. Discussions with SURF are in progress on this.
Fix the radio issue with the water treatment plant station. Vuk to contact Gary about this.
Potentially install other surface stations, depending on weather.
Improve the stability of the data flow.
3) Analysis of existing data
