During the few moments before and after totality, rippling patterns called shadow bands race across the ground. This citizen science project invites eclipse observers across Iceland and Spain to record shadow bands and help answer questions that remain largely unexplored Why Participate? • Witness one of nature’s rarest optical phenomena. • Contribute to genuine scientific research. • Help answer questions about how location and altitude influence shadow bands. • Be part of an international citizen science effort. • Receive detailed observing instructions before the eclipse. We're Looking for Volunteers • Locations near the eclipse centerline in Spain, Northern Africa, or Saudi Arabia. See the following published peer review paper on the image processing technique that will be used to analyze shadow band videos: https://link.springer.com/article/10.1007/s10686-026-10086-4 See the following for more details: https://joeengineerpilot.github.io/EclipseShadowBandTool/2027_Citizen_Science_Event.pdf
