SDO/HMI LOS magnetograms showing the magnetic fields of NOAA AR 11897. Red and blue solid curves outline the four locations of detected flux rope proxies in the AR from 14 to 19 November 2013. The red curves mean that the flux rope proxies on these locations can be detected only in hot EUV passbands, for example, 131 Å, while the blue curves mean that the proxies on these locations can be detected both in hot and cooler EUV passbands, such as 131 Å, 171 Å, and 304 Å. The temporal evolution of the LOS magnetograms is available as a movie (1.mp4) online.
