Professor Katherine Blundell received an OBE from HRH The Duke of Cambridge for services to astronomy and the education of young people. This was in recognition of her designing and directing Global Jet Watch.


Operation Solar Farmyard

We have installed a solar farm for GJW-IN. We collect light energy from our nearest star by day, and store this as chemical energy in big batteries to use by night to observe many different stars across our Galaxy.



All five of our observatories are equipped with Aquila spectrographs designed and constructed by Steven Lee of AAO.


Our fifth observatory

Our fifth observatory, GJW-WA, was enabled by a generous gift to the University of Oxford from Derek Benham of New York. Derek was a wonderful friend and supporter of Global Jet Watch. The whole team is very sad to learn of Derek’s passing, and we send our deepest condolences to his wife Joan.


The Global Jet Watch project consists of five observatories strategically distributed in longitude around Planet Earth, such that there is always one of these in darkness.  Optical astronomy has to be done at night!   Our observatories are equipped with research-grade instrumentation and telescopes.  They are located in the following places: 


If you are an amateur astronomer and you have a telescope, cooled monochrome CCD camera and narrow band filters and would be willing to collect some images for us over an extended period of time, we would be very interested in hearing from you. Please fill in this form, to indicate your interest and we’ll be in touch!
