             abstract = "We present, for the first time, observational evidence of a 
                         kinetic electric field near the X-line associated with asymmetric 
                         reconnection at the Earth's dayside magnetopause using Polar 
                         observations. On March 29, 2003, Polar satellite detected an 
                         asymmetric collisionless reconnection event. This event shows a 
                         unipolar Hall electric field signature and a simple deviation from 
                         the guide field during the magnetopause crossing, with the absence 
                         of an ion plasma jet outflow indicating that the magnetopause 
                         crossing was near the X-line. As expected from particle-in-cell 
                         simulations by Malakit et al. (Phys. Rev. Lett. 111, 135001 
                         (2013)), an earthward pointing normal electric field appears in 
                         the magnetospheric side of the ion diffusion region. The electric 
                         field satisfies two necessary conditions for the existence of the 
                         finite ion Larmor radius effect: (1) the ion Larmor radius (rg 2) 
                         is larger than the distance between the stagnation point and the 
                         edge of the ion diffusion region in the strong magnetic field side 
                         (´S 2) and (2) the spatial extent of the kinetic electric field 
                         (´EL) is of the order of the ion Larmor radius. Furthermore, it is 
                         shown that the peak value of the Larmor electric field is 
                         comparable to the predicted value. The observation of the Larmor 
                         electric field can be valuable in other analyses to show that the 
                         crossing occurred near the X-line.",
