Quantifying the Great American Solar Eclipse 2017




During the Great American Solar Eclipse of 2017, Dr. Bruce Bugbee, president of Apogee Instruments and a professor at Utah State University, deployed a suite of sensors in the path of totality in Rexburg, Idaho to measure various environmental parameters during the eclipse. In this video, Bruce discusses his findings. The Apogee sensors he used included spectroradiometers, a net radiometer, pyranometers, full-spectrum quantum sensors, infrared radiometers, and a precision thermistor inside an aspirated radiation shield.

Apogee Quantifies the Solar Eclipse

Apogee will be on site quantifying the Great American Solar Eclipse from the center of the path of totality on August 21, 2017. As one of the biggest solar radiation events of the century, Dr. Bruce Bugbee and NYU Professor, Dr. Tyler Volk, will be manning a full suite of Apogee radiation sensors including spectroradiometers, a net radiometer, pyranometers, quantum sensors, infrared radiometers, and a precision thermistor inside an aspirated radiation shield while in Rexburg, Idaho. Stay tuned for a full report and video of their results.
