2 November 2017: Support for the ephemerides of major planets was implemented in the user portal. When composing a request to observe a major planet, in the "Target" section of the request, select Type = "Non-sidereal" and then Scheme = "JPL Major Planet", and cells for the required orbital elements will appear. 

11 October 2017:  In requests for multiple exposures, users are now able to specify the "acceptability threshold."  The threshold is the percentage of the total time requested above which an observation is considered Complete and is not rescheduled. The default value is 90 percent. If an observation is interrupted before the time accrued exceeds the threshold, then the observation fails and is rescheduled. For more information, see the "Getting Started" guide.

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.

Siding Spring

30 Nov 2017: The 0m4b telescope (kb97 camera) is now available for science observations.

21 Oct 2017: The shutter on the fl12 Sinistro camera is stuck.

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. 


7-27 Nov 2017: The Sinistro camera in Dome C (fl06) failed.

27 Oct - 23 Nov 2017: Engineering team on site. Aqawan enclosure constructed. 0m4a (kb96) and ASAS-SN telescopes installed. Mirror in Dome B telescope replaced.

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.


30 Nov 2017: The 0m4b telescope (kb88 camera) is now available for science observations.

7-10 Nov 2017: The 0m4a telescope had to be taken offline. Some software bug is causing on-site image reduction processes to not get cancelled when they run too long, causing site software to grind to a halt. 

11 Oct 2017: The 0m4a telescope (with kb99 camera) is now available for science observations.

21 Sep 2017: The kb99 SBIG camera was installed in place of kb29. Commissioning of the new camera began.

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

Cerro Tololo

7 Dec 2017: The 0m4a telescopes (kb95 camera) is now available for science observations.

6-8 Nov 2017: Dome B could not be opened. Bolts holding the gears to the azimuth drive motor were loose. The bolts were replaced. 

22 Sep 2017: The first NRES spectrograph, fiber-fed from the telescope in Dome B, is now available to users (who have approved NRES proposals).

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.


24 Sep 2017: NRES spectrograph installation completed.

19 Sep 2017: 0m4a (kb80) telescope and ASAS-SN installed.

17-29 Sep 2017: Engineering team at site. Aqawan A enclosure constructed. 

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.


13 Nov - 7 Dec 2017: The 0m4b telescope (kb27 camera) was offline because of a problem with the focus mechanism.

7 Oct - 2 Nov 2017 - : The 2-meter telescope was out-of-service while the mirror was re-aluminized.

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.
