That interaction casues a change in the electron density profile of the C-H bond, withdrawing some of the electron density away from the H, and causing a small amount of deshielding, creating a small downfield shift for aromatic-bonded protons " vis-a-vis " those bonded to sp3 carbons . . . I don't see the source of the confusion here.

While passing behind Saturn ( as viewed from Earth ), " Voyager 2 " probed Saturn's upper atmosphere with its radio link to gather information on atmospheric temperature and density profiles . " Voyager 2 " found that at the uppermost pressure levels ( seven kilopascals of pressure ), Saturn's temperature was 70 kelvins ( " 203 �C ), while at the deepest levels measured ( 120 kilopascals ) the temperature increased to 143 K ( " 130 �C ).
