Network-wide:

23 Apr 2024: We are processing data with a new version of BANZAI. This version makes two improvements over the Feb 22 version:

  • The edges of the Sinistro detectors are masked for source extraction.
  • Errors in the aperture sizes used for (photutils) photometry have been removed.

6 Mar 2024: We have switched BANZAI back to a version that uses SEP. The newer version with photutils worked slower than expected, and at times of high volume, the pipeline would back up. We will re-deploy the photutils version after we've streamlined the code.

22 Feb 2024: The BANZAI pipeline now uses astropy's photutils package for source extraction and photometry instead of SEP. Also, the source catalogs (i.e. the CAT extensions of the FITS files) now include saturated sources, which are flagged with a value of 4.

4 Dec 2023: The Visibility Tool has been updated with the ability to look up the coordinates of catalogue targets. Also, the dates for seasonal and daily visibility can now be selected from a calendar.

2 Nov 2023: A software bug caused some images to be acquired with poor focus. We know of affected images from our sites in Chile (LSC), Texas (ELP), Maui (OGG), and Australia (COJ). If you have unusable out-of-focus data from this night, please contact science-support@lco.global.


Siding Spring

15 May 2024: New encoders have been installed on the 1-meter telescope in Dome A. The telescope will be unavailable until the pointing of the telescope has been established.

1 May 2024: Quick action has restored the coolant flow to the MuSCAT4 cameras. The instrument is available for science observations again.

30 Apr 2024: The temperature of the MuSCAT4 cameras is erratic. We have disabled MuSCAT4 until the problem(s) with the cameras are fixed.

30 Apr 2024: The guide camera on the Dome B telescope has been restored. Guided observations are possible again.

23 Apr 2024: The motion controller on the guide camera on the 1-meter telescope in Dome B is broken. The telescope cannot make guided observations until the guide camera is repaired.

18 Apr 2024: We have worked out a way to operate the site safely without requiring comms to the UPS. We are resuming science operations.

12 Apr 2024: We've lost communication with the facility's Uninterruptible Power Supply. For the safety of our hardware, we are keeping the site closed until the UPS can be inspected and comms restored. (The weather is bad, anyway.)

29 Mar 2024: The computer controlling the sq37 camera (on the 0m4b telescope) continues to behave erratically, which interrupt operations. The telescope had been taken offline until the problem is diagnosed and fixed.

21-24 Mar 2024: Cameras on the MuSCAT4 imager and the guide camera for the FLOYDS spectrograph warmed-up. The cooling system for these instruments was replaced, and the cameras are working again.

5 Mar 2024: The 1-meter telescope in Dome B is available for science observations again.

12-16 May 2024: The telescope in Dome A is unavailable for science while we diagnose the problem with the dome positioning (see below).

25 Apr 2024: NRES is available for science again.

24 Apr 2024: The site experiences a power outage at the end of the night. The NRES camera warmed-up, so NRES will be unavailable for a few nights until the camera is cooled and tested.

20 Apr - 12 May 2024: On these nights, a problem with the motion of Dome A was causing many observations at high airmass (i.e. low altitude) to be either partially or completely obscured. If you acquired images with the Dome A telescope on these nights, and your target was at an altitude < 45°, please inspect your images. If the stars have peculiar PSFs or the images are blank, contact science-support@lco.global for a refund of observing time.

18 Apr 2024: The acquisition camera for NRES on the Dome C telescope has failed. The input for NRES now comes from the telescope in Dome B.

25 Mar 2024: Power to the guide camera on the Dome B telescope has been restored, but there are still problems with the power supplies. Guided observations are possible again. The power supply will be replaced next week.

15 Mar 2024: Our full bandwidth to the site has been restored, but power strips in Dome B have malfunctioned, which will prevent us from making observations with this telescope.

13-14 Mar 2024: An unknown IT problem has crushed our bandwidth to/from the site, and observations were not possible on these nights.

29 Feb 2024: The focus of the guide camera on the Dome A telescope is unstable. Until this camera can be replaced or repaired, observations that require guiding will be scheduled on other telescopes.

19-20 Feb 2024: The computer controlling the NRES spectrograph was offline because of a failed power supply.

22 Jan 2024: The core computer has been replaced, and the telescopes are operational again. (Unfortunately, the weather is still bad.)

14 Jan 2024: The site's core computer is damaged. Observations are suspended until the computer can be repaired. (Weather is awful, so we wouldn't be observing anyway.)

18 Dec 2023: The fa08 Sinistro camera is available for science observations on the Dome B telescope.

17 Dec 2023: The fa16 Sinistro camera is now available for science observations on the 1-meter telescope in Dome A.

Haleakala

29 Apr 2024: A new guide camera for FLOYDS was installed on the 2-meter telescope. Camera testing will occupy the first part of the night.

3 Dec 2023: The storm has passed, and the site is open again. The MuSCAT3 camera is still offline. The narrow-band filters have been installed, but the camera focus must be improved before science observations commence.

30 Nov 2023: The Haleakala site has been closed and secured because of the threat from the Kona Storm.

25 Nov 2023: MuSCAT3 has been removed from the 2-meter telescope so that narrow-band filters can be installed. FLOYDS is still available for science observations.

13-16 Oct 2023: A problem with the oil system (Friday the 13th strikes!) kept the 2-meter telescope offline.
