Abstract The continuous and precise data were recorded by variety precursor instruments in the Hubei LocalEarthquakeprecursor Observing System during the 2009-2010 solar eclipse. After the careful processing and analysis for observations, three significant variations all related to the solar eclipse are found. Firstly,the geomagnetic anomaly valleys appeared before the eclipse starting. Secondly,during the total and annular solar eclipse, there were some differences between geomagnetic components and between microchanging geomagnetic anomaly phenomena. Before and after the total solar eclipse, there were clear features with shorttime and synchronization on the geomagnetic horizontal component. However, during the annular solar eclipse, geomagnetic declination component shows transitiontype change characteristics with trended and lagged. Thirdly,the solar eclipse made the tilt and strain of crustal deformation observations shorttime pulsate.
