Call for education partners 2018

The deadline has now passed and we are not accepting any more applications for this round.

More 0.4m telescopes

Three of LCO's 0.4m telescopes, which hitherto had made observations exclusively of satellites and space debris, are now making science observations. So, if you are an investigator on a project that was granted 0.4m-time, the scheduler may assign your observation requests to one of these "new" telescopes. The locations, camera codes, and dates of first observations for these telescopes are as follows:
  • Siding Spring (Australia); camera = kb97; start date = 2017-06-16.
  • Teide (Tenerife); camera = kb88; start date = 2017-06-20.
  • Haleakala (Maui); camera = kb82; start date = 2017-06-20.
BANZAI-processing of images from these telescopes has begun, and data are available in the archive.

The new portal is LIVE!

LCO's new observing portal is now available! Thanks for your patience while we brought the portal online. We think that you'll like it.

Coming soon: new user portal

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 you to use: to compose observation requests, to check the status of those requests, to retrieve your data, and to monitor the hours remaining for your science project. The big change for us here at LCO is that the new portal will be easier for our software team to maintain and improve.

FLUXAPER values in image headers

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 * arcseconds in diameter. For example, FLUXAPER3 is the source flux in a 3-arcsec diameter aperture. ----- The error in the pipeline was that the fluxes were being calculated within circular apertures of * pixels (rather than arcseconds) in diameter. So, in the example above, FLUXAPER3 was actually the source flux in a 3-pixel diameter aperture, even though the description in the header said 3-arcsecond diameter.
