New method (IMAGE) Frontiers Caption The novel imaging techniques applied to remote sensing data of the coronal mass ejection on 08 Oct 2016. A-D: Intensity of extreme UV (EUV; 21.1 nm) captured by the Atmospheric Imaging Assembly instrument on board NASA's Solar Dynamics Observatory. 1st column: 08 Oct 2016 15:00 UTC. 2nd column: 09 Oct 2016 00:00 UTC. 3rd column: 09 Oct 2016 09:00 UTC. 4th column: 09 Oct 2016 18:00 UTC. First row: unprocessed images. Second row: Difference images comparing EUV intensity to 12 h earlier. Third row: Images after Wavelet Packets Equalization (WPE), an image processing method. Fourth row: Images after Multi-scale Gaussian Normalization (MGN), another image processing method. Arrows denote dimmings and brightenings on the Sun's disc, previously overlooked but revealed with the new method. Credit Palmerio, Nitta, Mulligan et al.
