6 Aug 2019: The first "live" observations of the nascent AEON were a success! Science observations on the SOAR 4.1m telescope were scheduled in AEON-mode, with SOAR users submitting requests to LCO's scheduling software.
25 June 2019: The new Observation Portal was unveiled. The structure of the new portal allows non-LCO observatories to communicate with LCO's scheduling software and facilitates LCO's participation in AEON.
16 May 2019: The lifetime for Rapid Response observations has been extended from 6 hours to 24 hours.
30 Sep - 1 Oct 2019: The Dome A telescope got stuck on the roll axis and was unavailable for science observations.
12 Sep 2019: The Dome A telescope is back in service.
11 Sep 2019: Double whammy! The 1m telescope in Dome A is stuck, and the Sinistro camera on the Dome B 1m telescope warmed-up. Both telescopes are not available for science observations.
6 Aug - 8 Sep 2019: The fa11 Sinistro (on the Dome B telescope) had condensation on the CCD window. The camera was warmed-up and taken out-of-service.
31 Jul - 3 Aug 2019: Lost communication to site's UPS.
23 Jul 2019: The new camera (kb97) on the 0m4a telescope is ready for science observations.
15 Jul 2019: The camera (kb24) on the 0m4a telescope has condensation in it. The camera has been replaced with kb97.
28 Jun - 1 Jul 2019: The 2m telescope was not available for science observations because of a problem with the fiber optic cable.
6 Jun 2019: The 0m4b telescope (kb56 camera) is stuck on the pitch axis. This telescope has been taken offline.
29 May - 1 Jun 2019: A new back-up power supply for the clamshell enclosure was installed. The telescopes in the clamshell were not available for science observations.
9 May 2019: The computer controlling the 2m telescope went offline.
8-9 Apr 2019: The fa11 Sinistro camera on the Dome B telescope warmed-up and was taken out-of-service.
5 Apr 2019: The FLOYDS spectrograph, now with a new camera, is released or science observations.
3 Oct 2019: Science observations with the NRES spectrograph have resumed.
25 Sep 2019: The acquisition camera has been serviced. Tests of pinhole stability are in-progress.
6 Sep 2019: The pinhole on the acquisition camera is still unstable. An investigation is in-progress. The NRES unit is not available for science.
28-29 Aug 2019: The NRES unit was taken offline because the AGU pinhole is not stable.
2-20 Jun 2019: The NRES controller malfunctioned. The NRES spectrograph was offline until the controller could be replaced.
8 Sep 2019: The engineering team is on site for routine maintenance work. Some telescopes will occasionally be taken out-of-service. The team will remain until September 25.
6-9 Sep 2019: The fa06 Sinistro camera on the Dome B telescope warmed-up. The cooling system was replaced, and the camera is back in operation.
4-9 Sep 2019: The Dome A telescope was stuck at a limit on the pitch (Dec) axis.
19-22 Jul 2019: The Thorium-Argon reference lamp in the NRES spectrograph had to be replaced. Only imaging (Sinistro) observations were possible with the Dome C telescope.
12-31 Jul 2019: The telescope in Dome A gets stuck on the pitch axis before the start-of-night. A (manual) procedure is used to recover the telescope.
26 Jun - 1 Jul 2019: A mistake in the configuration of the fa14 (Dome B) and fa06 (Dome C) cameras was found. These cameras were unavailable while new calibration observations were made with the correct configuration parameters.
5 Aug 2019: The kb81 camera (on the 0m4a telescope) has been released for science observations.
30 Jul 2019: A faulty fan on the kb81 camera was replaced. The camera is now being tested prior to beginning science observations.
12 Jul 2019: The kb25 camera was removed from the 0m4a telescope and replaced with the the kb81 camera.
3 Jun 2019: The shutter on the kb25 camera is intermittently obstructing the field-of-view. This camera has been taken out-of-service until it can be replaced.
28 Aug 2019: The Dome B telescope is no longer exclusively for NRES observations. Requests for imaging with the fa04 Sinistro camera are now getting scheduled.
1-8 Aug 2019: The Dome B telescope was getting stuck at a limit on the pitch axis.
22-24 Jul 2019: There was a problem with the power supply for the NRES guide camera on the Dome B telescope.
3 Jun 2019: The telescope in Dome C was offline with a pitch axis fault. After that was cleared, pointing was off for most of the night!
13-18 May 2019: The NRES autoguider was not reaching its detent position and was taken offline.
17-23 Apr 2019: The fa15 Sinistro (on the Dome A telescope) warmed up and was not available for science observations.
26 Feb - 2 Apr 2019: The fa09 camera on the NRES spectrograph warmed-up. This NRES unit was taken offline.
10 Oct 2019: Dome B has been repaired/modified, and it can now move freely. Observations with ELP-NRES resumed using the Dome B telescope.
23 Sep 2019: Dome B is stuck again.
5-20 Sep 2019: The aqawan enclosure was triggering a fault. Observations with the 0m4a and ASAS-SN telescopes were suspended.
3 Sep 2019: The NRES guide camera on the Dome A telescope has ceased operating. ELP-NRES observations are not possible.
27 Aug - 22 Sep 2019: Dome B is stuck. The telescope was offline until the drive could be replaced.
23 Aug 2019: The Boltwood cloud sensors are no longer operational. It's possible for observations to be executed with cloudy skies. Other weather data (e.g. high humidity, high winds) will prohibit observations.
31 Jul 2019: The aqawan enclosure, containing the 0.4m telescope and ASAS-SN, triggered a fault condition.
13-17 Jul 2019: Dome B is stuck. The problem is under investigation.
10-18 Jul 2019: The guide camera on the Dome B telescope was mounted incorrectly, preventing guided observations.
