Winged hunters keep cockatoos at bay
A wedge-tailed eagle named 'Zorro' has been tethered to the 163-metre roof spire of the Melbourne Arts Centre after cockatoos took a liking to its thimble-size lights, chewing thousands of dollars worth of bulbs.
CABB
• Interim CABB (5 antennas, 1 IF) in parallel with existing system until shutdown next semester
• Details of interfacing CABB with current software to be determined
• ~25% of 2008APR proposals requested use of CABB• ~45% of 2008APR proposals requested 7mm or 3mm
observations• For 08OCT, propose to continue running interim CABB
system in parallel with existing correlator until ~6 week shutdown in mid-January. (Call for proposals to be released next week)

Seeing monitor
Two 1.8m fixed dishes on 230m E-W baseline operated at 30.48GHz since May2004
Seemon
• Optus B3 satellite being removed from service, has been moved from 152E to 164E
• Plans underway to use 21.2 GHz beacon on Optus C1 at 156E
• Parts arriving for new system, expected to be in place within a month
• Christoph Brem (occupational trainee) playing a big role in this
7mm system• 7mm automatic
translators operational
• ATCA calibrator database contains 7mm C007 data
• UCHII regions being investigated as 7mm and 3mm flux density calibrators

NASA tracking
• Learning curve about real-time self-cal on satellite signal at 32 GHz
• Ongoing proficiency test tracks at 8 GHz (Mars) and 32 GHz (Saturn)
• First “real” Cassini tracks in July/August 2008• Possibility of 8 GHz tracking support in the future • CA06 performance being studied• Kepler launch in February 2009 will have impact
on 08OCT semester schedule
WVRs
• Prototype Water Vapour Radiometers have been installed on CA03 and CA04 for a number of years
• ARC LIEF funding received, subject to ATNF PRB approval, to outfit all antennas with improved WVRs
Mopra • UPS replaced over the summer• 7mm receiver added (N.B. can’t centre 8GHz band
between 38 and 44 GHz)• HOPS 12mm observing over summer very successful• Telescope Operator Alerting Device (TOAD) in use• Mopra Training Day held in March, presentations
available on-line• MOPS era data now being added to ATOA• Mopra position now determined with sub-cm accuracy
Mopra in 08OCT
• Call for proposals to be released next week
• Limited 3mm observing over the summer
• Based on our experiences with the HOPS project, large proposals at 12mm (and 7mm?) encouraged
ATCA Science Day
• Wednesday 11 June
• All astronomers are invited to come and give science talks about the important projects they envisage doing with the Australia Telescope Compact Aarray (ATCA) in the next 5 years and beyond.
• See ATNF What’s On pages for more details
Narrabri Open Day --- Saturday July 19th, 2008. All welcome!
