Abstract
A total solar eclipse on 22 July 2009,the longest one of this century,occurred in East Asia and Pacific.Meanwhile,a medium magnetic storm arise in the late eclipse.The electron density profiles in maximum eclipse time were obtained from COSMIC radio occultation,and time series of TEC in local area was obtained from ground GPS stations of Wuhan CORS.And some physical mechanism of ionospheric effects during in the eclipse were analyzed.
