The High Performance Wireless Research and Education Network (HPWREN), a University of California San Diego partnership project led by the San Diego Supercomputer Center and the Scripps Institution of Oceanography's Institute of Geophysics and Planetary Physics, supports Internet-data applications in the research, education, and public safety realms.

HPWREN functions as a collaborative, Internet-connected cyberinfrastructure. The project supports a high-bandwidth wireless backbone and access data network in San Diego, Riverside, and Imperial counties in areas that are typically not well-served by other technologies to reach the Internet. This includes backbone locations, typically sited on mountain tops, to connect often hard-to-reach areas in the remote Southern California back country.

HPWREN Cameras are ideal instruments for demonstrating additional astronomical facts

The HPWREN camera archive contains millions of images that, when formed into time-lapse movies, can be used to illustrate subtle changes over long periods of time. Many examples of this have been created with a focus on the Earth, for example a La Cima time lapse video of the vegetation regrowth over many years after the Cedar Fire in 2003, but the images also capture some of the sky above.

Live Stream Videos

Fires, weather conditions, flooding, and other public safety conditions are scenarios where real-time sensor data distributions can become important aspects for situational awareness. HPWREN can now provide live feeds from most of its cameras, in addition to the post-processed videos shown at:

Can you see Comet NEOWISE?

This July 10, 2020 time lapse animation includes images that show Comet NEOWISE "" as seen from the newly upgraded wide-angle automated HPWREN cameras with better light sensitivity on Toro Peak. The HPWREN team was alerted to the Comet visibility by SDSU Mt. Laguna Observatory Director Robert Quimby, who himself got notified by former JPL employee B. Yen. The Comet can be seen directly with unaided eyes, and the Comet tail is visible with binoculars.

It shows 180 images each of the Toro Peak north and east HPWREN cameras for the 3AM to 6AM time period, which at more than 8,700 feet is at HPWREN's highest-elevation mountain-top camera location, as well as the color and monochrome imager chip versions. The 180 images times four cameras have been reduced in size from their original 3072x2048 pixel resolution to fit onto a 4k (3840x2160) canvas, and is animated at 7 frames per second. The Comet's tail starts to be visible around 3:30, but will be outshined by the rising sun around 4:48 (and earlier for the more light sensitive monochrome chip).
