====== Following on with another observation ======
Sometimes, another IVS observation will follow from the one just finished. In this case, some of the setup procedure will need repeating. Specifically:


=== e-Remote Ctrl ===
  * [[operations:eRemoteCtrl_newPCFSLog|Open a new PCFS log file]]
  * Next, [[operations:documentation.logmonitor_eremotectrl|set up the log monitor]] to provide warnings and alarms. you shouldn't need to restart it, but it will need to point to the new log file.
  * Now [[operations:starting_eRemoteCtrl_checklist|start the Checklist]]

The checklist should now be visible. The items in the list are described below and can be ticked off as you go. If time is pressing, skip items like pointing checks, fringe checks etc.

=== The Before Observation Checklist ===

== Prepare the schedule file ==

Hopefully this was already done well ahead of time and won't need doing now:
  * [[operations:documentation.ivs.drudg|Preparing the schedule and procedure files]]
  * On occasions, the Hobart data are written to disk between scans for e-transfer to Tsukuba for ultra-rapid EOP observations. Some additional changes to the schedule files are required in this case:
    * [[operations:documentation.ivs.drudg_ureop|Additional schedule preparation for Hb ultra-rapid EOP experiments]]
    * [[operations:starting_monitoring_urEOP|Additional tasks prior to starting Ultra-rapid EOP observations]]

== RF and IF signal path ==
Unlikely to need changing but worth a quick check:

  * [[operations:rf_if_check|Configuring the RF and IF signal paths]]

== Check the maser ==
Skip if time is pressing:

  * [[operations:maser_check|Hydrogen Maser check]]

== DBBC Configuration ==
If the DBBC config is the same as the last experiment, nothing to do here. However, if there is a change required, these are the steps:
  * [[operations:documentation.DBBCSetupIVS_v2|Configuring the DBBC]]

== Mark5 Recorder setup ==
This should only be necessary if the recording mode is different. It will be necessary to confirm that data are being recorded to the correct bank and you should have received notes on this prior to the experiment from the on-call person.
  * [[operations:documentation.ivs.mark5_v2|Mark5B recorder setup]]

== Clock and delay check == 
  * [[operations:documentation.clock_and_delay_check|Checking clock offsets and delays]]

== Test recording ==
If time permits (and can be safely skipped if the DBBC and Mark5 modes haven't changed):
  * [[operations:documentation.test_recording|Making a test recording]]

== System Temperature (Tsys) check ==
Skip if there isn't enough time:
  * [[operations:documentation.test_tsys|Tsys measurement]] check

== Antenna checks ==
Only check pointing if there's time:
  * [[operations:documentation.test_antenna|Antenna checks]]

== Weather checks ==
  * [[operations:documentation.weather_check|Weather conditions]]

== Fringe check ==
This is time consuming but worth doing if you have ~15 min to spare:
  * [[operation:fringe_checking|Fringe checking procedure]]

== Send a Station Ready email ==
Be sure to note any items skipped due to short change-over time (or recently checked):
  * [[operations:documentation.station_ready_email|Sending a station ready email to IVS]]

== Skype ==
  * Check all participating sites plus and the on-call person are included


===== Starting =====

The usual startup procedure can now be done: [[operations:documentation_ops2#starting_and_monitoring|Starting and Monitoring]]
