10 May 2018: A new version of the NRES pipeline was released. The new pipeline places all FITS files, including the extracted spectrum, in a single multi-extension FITS file.
26 March 2018: The coordinate look-up (on the observation request page in the user portal) now includes non-sidereal targets. After the target name is entered, the Type is set to "Non-Sidereal", and the Scheme is selected, the orbital elements of the target will be populated based on a query of the Minor Planet Center Database. (Support for major planets was added in November 2017.)
23 Feb 2018: LCO's weather pages have been redesigned.
19 Dec 2017 - 3 Jan 2018: Software deployed to the network on Dec 18 inadvertently caused some observations to be made with large pointing errors. The bug affected only observations on telescopes with multiple instruments (imager and spectrograph), and only observations made with the imager after a switch to the spectrograph (either FLOYDS or NRES). So, if no observation was made with a spectrograph until half-way through the night, then only imaging observations from the second half of the night are affected. The instruments and dates that were affected are the following.
10-11 December 2017: Power and internet outages kept the LCO headquarters closed. Network observations continued with the schedules that were available at the sites.
28 June 2018: The 2m telescope is available for science observations again!
21 June 2018: The Dome B 1m telescope is available for science observations again!
14 June 2018: The fl11 Sinistro camera (on the Dome B 1m telescope) is available for science observations again!
28 May 2018 - 22 June 2018: Engineering team at site. The optics renewal project, to replace/recoat the mirrors of the 2m and 1m telescopes, is in progress.
20 Apr 2018: The kb98 SBIG camera on the 0m4a telescope was dried-out and cleaned, after it was determined that condensation was behind the CCD window.
29 May 2018: There are problems with the focus mechanism in the 0m4a telescope. It will remain offline until it can be repaired.
12- Feb 2018: The mechanism for controlling the secondary mirror on the Dome B telescope is stuck. This telescope is out-of-service until the mechanism is replaced.
27 Nov 2017: NRES spectrograph commissioning begins.
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.
11 May 2018: The kb88 SBIG camera (on the 0m4b telescope) has moisture inside of it. It has been taken offline until it can be replaced.
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.
23 Apr 2018: Another SBIG camera, kb81, was installed on the 0m4a telescope in Aqawan A.
9 Apr 2018: The kb95 SBIG (on the 0m4a telescope in Aqawan A) has been removed because of condensation inside the camera.
31 Mar - 19 Apr 2018: Observations with the NRES unit were suspended because the ThAr arc lamp failed.
6 Dec 2017 - 17 Jan 2018: The fl09 camera in the NRES spectrograph warmed-up. The cryotiger system was serviced on January 15.
7 Dec 2017: The 0m4a telescope (kb95 camera) is now available for science observations.
20 April 2018: Commissioning of the new 1m primary mirror concluded, and the fl05 Sinistro camera resumed science observations.
2-13 April 2018: Engineering team at site. The primary mirror in the 1m telescope was replaced; the secondary mirror and the corrector plate were cleaned.
8 Nov 2017: The NRES spectrograph was released for science observations.
14 Oct 2017: The 0m4a telescope was enabled for science observations.
24 Sep 2017: NRES spectrograph installation completed.
3-12 Apr 2018: The 0m4c telescope was offline because of condensation inside the kb82 SBIG camera. The camera was dried-out and cleaned.
12-20 Feb 2018: The computer controlling the guide camera for the Spectral imager died and had to be replaced.
17-24 Jan 2018: The 0m4b telescope was stuck on the pitch axis.
9 Dec 2017 - 15 Jan 2018: The 0m4b telescope (kb27 camera) was out-of-service again because of a problem with the cables to the focus/collimation motors.
13 Nov - 7 Dec 2017: The 0m4b telescope (kb27 camera) was offline because of a problem with the focus mechanism.
