The Australia Telescope Compact Array ( ATCA ) is a radio interferometer consisting of six 22-m antennae aligned along a 6-km-long, east-west track. ... The ATCA Upgrade , which is part of the Major National Research Facility ( MNRF ) program, will allow astronomers to observe at even higher frequencies, around 22 GHz (12 mm) and 90 GHz (3.5 mm). ... The ATCA Upgrade will open a number of new opportunities; these are set out below. ... The ATCA Upgrade involves the following projects: . ...

... The Russian TESIS/ CORONAS-PHOTON Solar Observatory, which has been working in orbit since January 30th, 2009, has photographed one of the most important events in the build up to the upcoming solar cycle - the formation of our star's new southern belt of activity. The first magnetic fields of the new cycle in the southern hemisphere appeared on the Sun's surface on May 23-24th. ... The belt of activity is one of the primary concepts, characterizing the solar cycle. ...

... The SMS program is a critical endeavor to investigate whether the predictions of standard cold dark matter cosmology are consistent with the observed matter distribution in the Milky Way halo. It is the deepest, most extended search for optically elusive dwarf satellite galaxies and tidal streams to date, covering the entire Southern hemisphere. ... However only a few dwarf satellites have been found around the Milky Way to date - 22 dwarfs compared to 500-10,000 predicted by theory (Klypin et al. ...

... A similar level of effort is anticipated for HDF-S. We are maintaining a `clearinghouse' for supporting and follow-up observations of the HDF-S. Test observations of the HDF-S field were obtained in October, 1997. ... Simultaneous, parallel observations were made with the three HST instruments STIS, WFPC2 and NICMOS of separate, neighboring fields. ... Additional flanking field observations were made surrounding the deep STIS, WFPC2 and NICMOS fields. ... The red field is the main HDF-S WFPC2 field....

... Over the course of a week two secondary students James Hadnett and Liam Fields observed NEAs using one of two 2-Metre telescopes courtesy of the Faulkes Telescope Project which are positioned in the Northern and Southern Hemisphere. This was made possible with the aid of Las Cumbres Observatory who, with their Global Telescope Network, give educational establishments the chance to observe with a high grade telescope. ... Comet C/2012 F6 (Lemmon) observed on 2013 July 1st. ... 2013 July 5th . ...

Brad Carter, Carolyn Brown, Rhodes Hart Drew Foster, John Kielkopf, Ron Moore University of Southern Queensland, Australia University of Louisville, Kentucky, USA OVERVIEW Mt Kent Observatory is now providing live remote observations of southern skies as part of a collaborative project between USQ, the University of Louisville, and Northern Kentucky University. ... This enables observers to make daytime use of a remote telescope during its local night-time, and image otherwise inaccessible skies. ...
