  In this study, we investigate an extreme ultraviolet (EUV) wave event on 2010
February 11, which occurred as a limb event from the Earth viewpoint and a disk
event from the STEREO--B viewpoint. We use the data obtained by the Atmospheric
Imaging Assembly (AIA) aboard the Solar Dynamics Observatory (SDO) in various
EUV channels. The EUV wave event was launched by a partial prominence eruption.
Similar to some EUV wave events in previous works, this EUV wave event contains
a faster wave with a speed of $\sim$445$\pm$6 km s$^{-1}$, which we call
coronal Moreton wave, and a slower wave with a speed of $\sim$298$\pm$5 km
s$^{-1}$, which we call "EIT wave". The coronal Moreton wave is identified as a
fast-mode wave and the "EIT wave" is identified as an apparent propagation due
to successive field-line stretching. We also observe a stationary front
associated with the fast mode EUV wave. This stationary front is explained as
mode conversion from the coronal Moreton wave to a slow-mode wave near a
streamer.
