In June, LCO will unveil a new observing portal, the interface through which you interact with the Network. This new portal has been developed (under the codename "Valhalla") over many months. We expect that the re-designed portal will be easier for

FLUXAPER values in image headers

19 May 2017
We recently discovered an error in our BANZAI data pipeline. In the source catalogs (i.e. the .CAT extensions) that accompany the reduced images, the set of FLUXAPER* keywords are used to indicate the source fluxes within circular apertures of * arcs

12 May 2017
We have had to discontinue observations with the telescope in Dome C at our Chilean site (LSC). The Sinistro camera in that dome (fl04) appeared to have a steep drop in temperature on 2017-05-07. The drop was actually a symptom of a problem with a ci

FLOYDS "sky" mode fixed

28 Apr 2017
We have debugged the "Sky" slit positioning mode on FLOYDS. "Sky" mode allows you to fix the position angle of the slit. (The more commonly-used mode sets the slit at the parallactic angle.) The change will take effect with FLOYDS observations beginn
