• Tidbinbilla (NASA) -- limited access
• Hartebeesthoek (S. Africa) Kokee Park (USNO)
• adhoc others
• Observations 5-10 days /term

LBA Proposals

• Proposals through ATNF ATAC
• -- (1-year lifetime)
• 6 new proposals /term
• e.g. 7 just received for next term
• Overall oversubscription rate - 2
• Schedule time on 5-6 proposals/term
• Multi-term and Long term proposals
• e.g V131 (astrometry/imaging) - 5 year
  project!

Observations

• Observe at all AT-bands
• - 1.4, 1.6, 2.3, 4.8, 6.0, 6.7, 8.4, (12), 22
  GHz
• Recent 22 GHz observations
• - multiplexed observations of 4 lines
• - autocorrelations at Pa, Mp, Cd, Ho, Tid
• ATCA data
• New 22 GHz Rxs at Tid, Ho and Cd
• - very sensitive Tid Rx
• Correlation progress still slow (people?)

People movements

• Steven Tingay - ATCA ? Swinbourne
• Richard Dodson - UTas ? Japan
• Hayley Bignall (UAdel) ? JIVE
• Tracy Getts effectively left
• Paul Jones 6 months LBA correlator
• Chris Phillips Bolton fellow (technical)

VSOP

• NASA support ceased Feb 2002 (5 years)
• Survey program continues
• - S2 recording Canadian correlator
• - until Feb 2003
• Request for Mopra support through ATAC
• LBA Mp, Ho, (Hh)
• Since Feb 29 obs at Mp 1 in Dec
• Since Aug only 6 obs (1)
• Winding down?

LBA Future

• New technologies (Disk recording fibres)
• - 1 Gb/s rates (vs. 128 Mb/s now)
• NTIV (New technologies in VLBI) meeting in Korea
  (5-8 Nov 2002) 6 people from ATNF
• LBA strategic plan?
• - open meeting(s) planned early 2003
• - will report to next ATUC (Steering Ctee?)
• Plan LBA path for near future
• Far future is SKA?
