12 September 2017: The new Scheduler Visualization has been unveiled! The Visualization shows you at a glance what's happening on LCO's network. 

19 July 2017: Plots and data tables from transmission measurements of LCO's deployed filters are now available for download from the filters webpage.

5 June 2017: The new user portal is now available! Read the Getting Started guide for information on how to use the portal.

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.

Siding Spring

7-8 Sep 2017: Additional Spectral camera (fs01) warm-ups during nighttime hours.

31 Aug 2017: The Spectral camera (fs01) again warmed-up. Observations made on this night were affected by fluctuating temperatures.

29 Aug 2017: The Spectral camera (fs01) was out-of-service because of a problem with the cryo system. Observations made on the nights of Aug 20, 21, 26, 27, 28 may have been affected by fluctuating CCD temperatures.

24-31 Aug 2017: FLOYDS was intermittently taken offline so that the newly-installed tertiary mirror could be inspected. The replacement mirror was discovered to have a different response from the original, so the original was put back in place. 

7-9 Aug 2017: New tertiary mirror installed. The aluminum coating on the original tertiary was discovered to be flaking off during a routine inspection on July 29. FLOYDS was unavailable while test spectra were obtained.


9 Aug 2017: The site is unavailable for science observations tonight while our IT team makes computing infrastructure changes in preparation for new instrument installations.

5- June 2017: The Sinistro in Dome B (fl14) has a CCD readout problem. This camera has been taken out-of-service.

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!


27 July 2017: The 0m4a telescope (camera kb29) was taken offline because of dew on the CCD window.

20 June 2017: The 0m4b telescope (camera kb88) began science observations. It will be used intermittently for satellite observations.

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.

Cerro Tololo

30-31 Aug 2017: Observations from the Dome C telescope are suspended while the primary mirror is replaced.

26 Aug - 4 Sep 2017: Engineering team at site. Aqawan B enclosure set up; installation of ASAS-SN and 0m4a (kb26) telescope. Dome C primary mirror replacement. Dome B Sinistro swap.

3 Aug 2017: Science observations with the fl03 Sinistro camera (now on the Dome C telescope) resumed.

1 Aug 2017: The fl03 Sinistro camera was transferred from the Dome B telescope to the Dome C telescope. The fl04 Sinistro camera went from Dome C to Dome B.

27 July 2017: The fl03 Sinistro camera (Dome B) was warmed-up in preparation for transfer to Dome C telescope.

14 June 2017: The telemetry board on the fl04 Sinistro (Dome C) appears to have failed! This camera is out-of-service.


17 -29 Sep 2017: Engineering team at site. Aqawan A enclosure constructed; installation of ASAS-SN camera and 0m4a (kb80) telescope.

19-27 June 2017: The camera (fl05) temperature is unstable when the ambient temperature in the dome is high (it's summertime in Texas!), sometimes warming by as much as 9 C. The temperature has stabilized since the dessicant in the cryo system was recharged on June 27.


29 Aug - 8 Sep 2017: There was a problem with the computer controlling the 2m telescope. Science observations were suspended.

25 Aug - 12 Sep 2017: Because of a problem in the electrical cabinet, the pitch axis of the 0m4c telescope was stuck. 

30 July 2017: The clamshell remained closed overnight because of a cultural prayer session on Haleakala.

3 July 2017: The 2m telescope was taken offline because a broken link in the cable wrap restricted its range of motion.

20 June 2017:  The 0m4c telescope (camera kb82) began science observations. It will continue to be used intermittently for satellite observations.
