16 Mar 2020: In response to the COVID-19 pandemic, LCO employees have been asked to practice social distancing, and those who are able to work from home are doing so.
17 Dec 2019: We've simplified the procedure for repeating a sequence of exposures. By setting an observation request's type to "Exposure Sequence", the instrument configurations (i.e. filters, exposure times, etc) are repeated as many times as possible for a user-specified duration. For more information, check the "Getting Started" guide or the Developers page.
19 Nov 2019: The Sinistro camera on the 1-meter telescopes can now be used in a "fast cadence readout mode." The mode reads the central 2048 x 2048 pixels, with 2x2 pixel binning, and with a readout overhead of 9 seconds. For more information, see the Sinistro webpage.
5 Nov 2019: Observation requests can now be composed with multiple Instrument Configurations for each Configuration. This feature allows, e.g., a series of exposures to alternate between filters without requiring the target to be re-acquired.
