 +**Actions arising**
 +
 +CARRIED FORWARD/UPDATED/CONTINUING
 +
 +  *  LBA data archive consolidation and copy at CASS. (CASS, Curtin)
 +    *  LBA data archive. Need ATNF disk space (Tasso, Shaun) ** Continuing **
 +
 +  *  ATCA phasing. Check performance and implementation (Jamie S, Richard)** Updated **
 +    *  Definitely need >200 mJy calibrators. Stress in documentation. (ATNF)
 +    *  Recommend strong calibrators >> 200 Mjy ~every hour (depends on weather) + possible weaker calibrators more often (ATNF)
 +    *  Ask PIs to nominate phase-cals and check fluxes BRFORE scheduled observations (Phil, Jasmie S)
 +
 +  *  ATCA Tsys via CABB (CASS) ** Updated **
 +    *  Investigate implementation by Bob Sault (Tasso)
 +    *  Consult with Carrad and Sault about Tsys implementation on the CABB (Tasso) 
 +    *  Check with WEW and test whether acal scale preserved when mode changed to VLBI (Jamie S)
 +    *  Review ATCA VLBI configs (Jamie S, Tasso)
 +
 +  *  Observer training and remote observing (Tasso) ** Continuing **
 +
 +  *  Wiki logs (All) ** Continuing **

 +
 +
 +
 +NEW ACTION ITEMS
 +
 +  *  DASPRO for Parkes needs updating to reflect Mars Rx changes (Chris)
 +
