The derived temperature maps are quite similar to the ones obtained earlier with a different methods, the main differences occurring in the spot latitudes and relative strength of the spot structures....

Dimmings or transient coronal holes (i.e. regions of decreased intensity of soft X-ray and EUV emission), which are observed on the solar disk after halo coronal mass ejections (CMEs), are analyzed using SOHO/EIT data simultaneously in three coronal lines Fe IX/X (171 A), Fe XII (195 A) and Fe IX (284 A) sensitive to temperatures Te~1.2, 1.5 and 2.0 MK, respectively, as well as in the transition region line He II (304 A; Te~(0.02-0.08) MK). ...

This diagram illustrates two block boxes, one above the other, with rectangular clipping regions of different dimensions. ... Both axes depict increments of 5px. The clipping region of the first P box lies entirely within it, offset 5px from the top and left edges of the P box, and 10px from the right and bottom edges. ... The clipping region of the second P box resembles that of the first in style and position, except that the right edge is 5px to the right of the P box's right edge. ...
