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: More power and internet outages kept the LCO headquarters closed. Network observations continued with the schedules that were available at the sites.
5 December 2017: There were power and internet outages at LCO headquarters because of the nearby Thomas fire. The offices were closed.
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.
13-15 Feb 2018: The fl12 Sinistro was offline because the cooling system couldn't maintain a steady temperature.
5-7 Feb, 15-16 Feb, 19-23 Feb 2018: The controller for FLOYDS is intermittently malfunctioning.
21-23 Jan 2018: Because of the threat from nearby bushfires, the site was closed.
15-20 Jan 2018: The computer that controls the 2m telescope was shutting itself down.
11-26 Jan 2018: The guide camera for FLOYDS was broken. The camera was replaced on Jan 19; testing was possible after the site re-opened on Jan 24.
4 - 24 Jan 2018: the fl12 Sinistro camera warmed-up and was unavailable for science observations.
4 Jan 2018: Because of the amplifier problems that started on Dec 29, the fl11 camera was taken out-of-service.
3 Jan 2018: The fl12 Sinistro camera (Dome A telescope) was returned to service.
29 Dec 2017: The fl11 Sinistro camera (on the Dome B telescope) failed during start-of-night flat field observations.
20 Dec 2017: The 0m4a telescope (kb98 camera) is stuck because of a problem with the Motion Interface Computer.
12- Feb 2018: The mechanism for controlling the secondary mirror on the Dome B telescope is stuck.
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.
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 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.
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.
19 Sep 2017: 0m4a (kb80) telescope and ASAS-SN installed.
17-29 Sep 2017: Engineering team at site. Aqawan A enclosure constructed.
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.
7 Oct - 2 Nov 2017: The 2-meter telescope was out-of-service while the mirror was re-aluminized.
