Computing Infrastructure
• New wireless network at Marsfield with the ESSID of "Guest
Network". Visitors will need a staff member to create a temporary
login name and password. The 'pink cable' wired network for visitors
is still in place and requires no username or password for use.
• The SSH gateway host venice.atnf.csiro.au has been replaced –
contact [email protected] if any problems
• The UNIX password-changing system (‘passwd’) on venice has
been upgraded. Auto-expiring passwords after 1 year is under
consideration. Users can still change their NEXUS domain (Windows)
password on venice, using the same 'nexuspasswd' program.
• NRAO has released version 4.1 of their CASA package, which
contains numerous new features that will be useful for processing
ATCA data. The new version is available on ATNF systems.

Time Assignment Committee
• TAC met in February to review proposals for 2013APR
• ATCA statistics:
•
•
•
•
116 proposals submitted, 11 of which were NAPAs
Time requests ranged from 4 hr to 255 hr, median 41 hr
62 proposals allocated at least some time (allocations from 5 hr to 243 hr)
All projects with grades of 3.7 or higher were allocated most of their
requested time. Most projects with a grade of 3.6 were allocated some of
their requested time. Few projects with grades below 3.6 were able to
be allocated any time.
• Last meeting for Jessica Chapman as TAC Executive Officer!
• Deadline for 2013OCT proposals Monday June 17, 5pm AEST
• Reload all cover sheets into editor to ensure all questions answered

Science Operations Centre
• First Parkes remote observing (still requiring a person in the tower)
in December 2012.
• Use of the SOC for ATCA, Mopra and ASKAP observing
• Split system air conditioners about to be installed in control rooms
• Security card readers to be added to either end of “SOC corridor”
• SOC user guide at http://www.atnf.csiro.au/observers/SOC/
• SOC Support from rostered Astro group member, designated
“friend”, or operations staff
• SOC selectable as site on existing Fault Report form

Parkes
• Update on RAPT project and TPS given by Douglas
• Expect MB20, 10/50, and H-OH to be available in 2013OCT, with
the availability of other receivers driven by proposal pressure.
Highly graded proposals requesting a receiver that is not installed in
the focus cabin in 2013 APR don’t need to be resubmitted. (There
was one proposal in this category in 2013APR.)
• Changes in OPAL to cover sheets, including addition of designated
project expert for each proposal
• HIPSR commissioning of wide-band mode well underway;
development of narrow-band modes in progress.
• Expect Parkes remote observing, beyond the SOC, to require
annual re-qualification, as for ATCA

Visitor Services Group
• Parkes Quarters changes
• From 1st October 2012 the Parkes Quarters provides accommodation,
breakfast and evening meals but no longer provides lunches.
• Lunches for observers, Parkes Observatory staff, and other visitors are
available from the Dish Café.
• From 1st October 2013 the provision of dinners will also cease.
• The Quarters will be operated in the same way as the Marsfield Lodge, with
cereal, milk, juice and bread provided for breakfasts.
• Changes will be made to the kitchen to enable visiting staff to self-cater for
lunches and dinners if they wish to -- alternatively, meals can be purchased
from the Dish Café.

ATCA
• All antennas now outfitted with new 4cm-band receivers, replacing
the old 6cm/3cm (“C/X”) receivers.
• Prototype 4cm band feeds on CA03 and CA05, to extend frequency
coverage at top of band to 12 GHz – need to adjust focus on these
antennas when moving to or from 4cm
• Reprogramming CABB to zoom bands (1MHz or 64MHz) still time
consuming and requires expert knowledge. Additional explanation
on zoom bands on CABB web page.
• “Water Vapour Radiometers for the Australia Telescope Compact
Array,” Indermuehle et al. arXiv:1212.6101
• ATCA update emailed to users last month
• Plea for users to update their details in OPAL
• Regular plea for observers to complete Observer Feedback form

Qualifying for ATCA remote observing
It is clear the current requirement is not sufficient, which has led to
the suggestion of a points-based qualification system. An example
might be that 100 points are needed to qualify, and:

Mopra
• Funding has been secured to operate the Mopra Telescope for
three years, commencing in October 2012. Mopra operations will
initially be supported by NAOJ and UNSW/Adelaide consortium.
• Mopra observing started with a block on UNSW/Adelaide time on
May 7th.
• Schedule for 2013APR semester released May 23rd. ATNF time has
been allocated for single dish observing in July, and LBA blocks in
June and August.
• Next call for Mopra proposals for ATNF time, 2014APR.
• “Characterization of the MALT90 Survey and the Mopra Telescope
at 90 GHz” PASA, in press (arXiv:1306.0560)

Tidbinbilla
• The 70-m returning to service.
•A new K-band system with new ROACH/CASPER board
spectrometers being installed.
• 70-m L-band narrowband filter replaced to give a 1325-1925 MHz
coverage (LCP only).

• http://www.atnf.csiro.au/research/conferences/2013/rfi2013/index.html

•Recent papers:
• “Discovery of four water masers in the Small Magellanic Cloud,” Breen et al. (arXiv:1304.1213)
• “Submillimeter H2O Maser in Circinus Galaxy - A New Probe for the Circumnuclear Region of
Active Galactic Nuclei,” Hagiwara et al. (arXiv:1305.0076)

Long Baseline Array
• 7-day session in March 2013 (no Mopra…), next session starts this
week
• 6cm/3cm (“C/X”) band receiver re-installed on Mopra, but
20cm/13cm (“L/S”) receiver currently removed.
• L-band tertiary system installation completed at Ceduna
• Two LBA ToO observations recently (with subset of LBA)
• Occasional out-of-session RadioAstron observations with a subset
of LBA
• XCube testing for next generation wideband recorder

ASKAP
• Formal transfer of staff from ASKAP project into Operations Theme
• Science Operations staff will participate in ASKAP commissioning
• Involvement of Science Operations staff with ASKAP scheduling,
operations, documentation, etc. over the coming months
• Continued use of a single ASKAP antenna in LBA observations at
20cm or 3cm (on non-interference basis)
