We investigate the coronal wave associated with the February 15, 2011 X-class flare. The flare occurred at 1:44 UT in active region NOAA 11158. We use observations from the Atmospheric Imaging Assembly (AIA) aboard Solar Dynamics Observatory, and the Extreme Ultraviolet Image (EUVI) aboard the Solar Terrestrial Relations Observatory to study the propagation of the coronal wave over the entire solar surface with the help of full Sun synoptic maps. The high-cadence AIA observations allow us to examine the temporal evolution of the wave in great detail. Our investigation focuses on two aspects: (i) The apparent transmission and reflection of the wave through a coronal hole, and (ii) the thermal response in the corona during the coronal wave passage.
