25 Apr 2017: The qualitative descriptions of FLOYDS slit sizes, e.g. "Floyds_large_slit", have been retired. The quantitative descriptions (1.2, 1.6, 2.0, 6.0 arcsec) are exact and less likely to confuse.

1 Apr 2017: The 2017AB observing semester begins! We have also decreased the default airmass limit for observing requests from 2.0 to 1.6. We encourage users to consider airmass limits carefully when composing observing requests, but we've noticed that many users keep the default.

30 Jan 2017: The "Getting Started on the LCO Global Telescope Network" guide has been updated. It is available from the website's Documentation page.

8 Nov 2016: LCO users can now update their email addresses in the portal without requesting assistance from science-support.

17 Oct 2016: When composing an observing request, users can now specify a minimum acceptable angular separation between the science target and the moon. This constraint is labeled "Minimum Moon Distance" in the portal. The default value is 30 degrees.

Siding Spring

17 Feb 2017: The kb94 camera (on the 0m4b telescope) was removed, and kb97 was installed in its place.

4-8 Dec 2016: The 2m telescope was offline because of unexpected "overspeed" events (in telescope motion).

1 Dec 2016: Science observations began with the kb98 camera on the 0m4a telescope.

21 Nov 2016: The kb98 camera replaced kb84 on the 0m4a telescope.

11 Nov 2016: The kb94 camera was moved from the 0m4a telescope to 0m4b. The kb84 camera, which was on 0m4b, was removed. The 0m4b telescope continues to make satellite observations.


19-23 May 2017: The replacement for the pubsub computer died.

27 April - 2 May 2017: One of the main site computers died on 2017-04-27 at 23UT. The computer was rebuilt, and science observations resumed during the 2017-05-02 night. 

27 Oct 2016: The fl16 Sinistro in Dome A has been released for science observations!

24 Oct 2016: BANZAI-reduced images from the fl14 Sinistro (Dome B) are now available in the archive.

18 Oct 2016: The fl14 Sinistro camera in Dome B is now available for science observations. The images will be BANZAI-processed when all flat fields have been acquired.


1 Nov 2016: The 0m4a telescope (camera kb29) is again available for science observations.

24-28 Oct 2016: TFN site maintenance trip.

17 Oct 2016: Teide (TFN) has been added to our Target Visibility Tool. The visibility of a target from TFN is indicated in orange.

11 Sep 2016 - : The 0m4a telescope is getting stuck along the roll axis. The telescope is currently not available for science observations.

Cerro Tololo

7-12 May 2017: The Dome C Sinistro (fl04) cooled unexpectedly at 16:23 UT on May 7. The telescope has been taken offline while the problem is being investigated.

25 Apr 2017: The Dome A Sinistro (fl15) was taken out of service.

13 Apr 2017: Strange pattern noise becomes more prevalent in fl15 (Dome A Sinistro) images. 

28-29 Mar 2017: No observations were possible because of problems with one of the on-site computers.


1 April 2017: Everything okay at the start of the 2017AB semester.


29 April - 2 May 2017: A power supply in the clamshell failed. Observations were not possible until a replacement was purchased and installed.

28 April 2017: Breaker tripped! The clamshell closed at around 11 UT.

15-26 Feb 2017: The Spectral camera (fs02) on the 2m telescope warmed-up again(!) and was taken offline.

6-8 Feb 2017: The Spectral camera on the 2m telescope warmed-up and was offline.

20-24 Jan 2017: 0m4b telescope was out-of-service because of pitch axis error.
