We have changed some telescope efficiencies recently to reflect the actual data extracted from images. Normally, the efficiencies are updated automatically, and these updates are smooth and do not significantly change the values once they are well established. However, we haven't yet accumulated enough data points to let this process run automatically for several telescopes for which the initial guess for the efficiency was clearly off. For these telescopes, we had to do this one-time update.

As a result, all new observations submitted to these telescopes will cost you more than before -- sometimes, significantly more, except for PROMPT-USASK. Moreover, if you have a long-running observation on multiple telescopes and/or choose exposure length for the Generic 16-inch w/back-illuminated CCD instead of choosing it for a specific telescope, exposure lengths will be scaled according to the new efficiency when dispatching the exposure, so they might be different than before for the same telescope. If you have such long-running observations, we suggest you to cancel and resubmit them to make sure that all exposure lengths are as you expect.

We apologize for any inconvenience this may have caused. Once again, this is a one-time change; future updates will not change these values significantly unless something serious happens, like replacing the camera.

Below is the list of affected telescopes; by definition, PROMPT5 = Generic 16" has the efficiency of 1.

PROMPT telescopes at CTIO are back online after a 7-month shutdown.

Congratulations to L. Tartaglia (TTU, UC Davis), D. Sand, S. Wyatt (TTU), S. Valenti, K. A. Bostroem (UC Davis) for their discovery of the brightest type Ia supernova thus far this year.  It was initially detected on March 10, 2017 in NGC 5643 during PROMPT5's nightly surveying campaign and is now brighter than magnitude 12 making it an excellent target for both professional and amateur astronomers around the world.

Tia Bertz and Chris Mathews are two incredible Skynet Junior Scholars who attended the 2016 STEM Career Showcase for Students with Disabilities yesterday at the North Carolina Museum of Natural Sciences.  We could not be more proud of them and their accomplishments.  You can watch their presentations below.

Though a partnership with the Athabasca University and a generous donation from Dr. Ryan Boland of Savannah, Georgia,  Skynet deployed a 16-inch RCOS telescope in Alberta Canada.  Expect to see the new system come online within the next month.

The Robert Martin Ayers Science Fund is sponsoring at least 100 hours of observations with the PROMPT telescopes for researchers and students not at PROMPT Collaboration institutions.  Preference will be given to those at institutions without comparable facilities and resources.  For more information,  you can download the proposal form here: http://user.physics.unc.edu/~reichart/ayers.doc.
