We present high and moderate spectral resolution spectroscopy of diffuse ionized gas (DIG) emission in the halo of NGC 891. The data were obtained with the SparsePak integral field unit at the WIYN Observatory. The wavelength coverage includes the [N II]λλ 6548, 6583, Hα, and [S II]λλ 6716, 6731 emission lines. Position-velocity (PV) diagrams, constructed using spectra extracted from four Spars...

The methods and software interfaces used by ocean observatory operators and scientist users to access data generated by sensors and instruments attached to research observatories vary widely from facility to facility. The tools used to access instrument metadata and to control various instrument functions are also variable between observatories. An effort has begun in the US to define software ...

The 1.0 metre f/4 fast-slew Zadko Telescope was installed in June 2008 approximately seventy kilometres north of Perth at Yeal, the Shire Gingin, Western Australia. Since has been operation it proven its worth by detecting numerous Gamma Ray Burst afterglows, two these being most distant `optical transients' imaged an Australian telescope. Other projects include a contract with European Space A...

We present time resolved optical data acquired by the TAROT automated observatory on the afterglow of GRB 050525a from 6 to 136 min after the GRB. We find evidence for a rapid re-brightening of 0.65 mag of the afterglow at ∼33 min after the GRB. The decay slope α is 1.14 ± 0.07 in the first part and is 1.23 ± 0.27 after the re-brightening event. The afterglow of GRB 050525a is the third known a...
