On April 8th, much of North America was treated to a solar eclipse. Those lucky enough to be in the path of totality were treated to a total eclipse for as many as 4 minutes.

I was able to view the total solar eclipse from northern New Hampshire, a few miles from the Canadian border. We were fortunate to have clear skies for an unobstructed view of the eclipse. I brought along an ILT2500 with the SED033/Y/W detector, our ISO/IEC 17025:2017 calibrated, photopically-corrected lux sensor with wide-eye diffuser, to record the event and see the changes in light level over time. The graph below charts the event from about 10 minutes prior to the start of the eclipse with full sun. The graph shows the light level slowly and steadily decreasing over the next hour. At totality, the meter reads zero lux before slowly returning to full sun again about an hour after totality.
