Duty astronomers at the Compact Array are rostered from ATNF staff and students to provide support to observers at Narrabri for periods of one week at a time. The duty astronomers are required to assist observers prepare observing schedules, help set up the Compact Array at the start of an observing run, diagnose and attempt to solve problems that arise in the course of the observations and help observers with the initial analysis of their data. ... www.atnf.csiro.au/observers/tidbinbilla . ...

ACTIVITY TITLE: Thermal Verification ID: TCS-01 APPLICABLE REQUIREMENTS: L.10.4.13.1 DESCRIPTION: The determination of the impact of NOBL installation is expected to be ongoing for Bays 5, 7 and 8, likely through and past the SMOV period. ... Bays 5 and 8 are expected to have greater impact following successful installation of the NOBL-ER. Since the changes are not expected to have critical impacts, no specific thermal verification is really warranted for the SMOV period. ...

... The Sun has come all of one day away from breaking its record for the longest period of inactivity for the last decade - reaching a mid-summer low and falling into yet another state of "hibernation". Yesterday, on the first day of autumn, new sunspots appeared on the surface of the Sun following an absence of almost 50 days. ... The first low lasted 51 days, from 21 July until 11 September last year. ... Now, almost a year later, it seems the Sun has hit a new low almost as "deep" as the first. ...

... Rates are estimated to be from 50-100 meteors per hour in prime observing conditions. But this is the so-called ZHR, or Zenithal Hourly Rate, which is the number of meteors per hour which would be seen by an experienced observer, with the radiant in the zenith, in a perfectly clear dark sky. ... The peak is expected to be at 23.30 UT so as the radiant (in the 'Sickle' of Leo) will not even have risen from most of Ireland by then, we will see very few meteors, if any, at that time. ...
