AB: Although the solar disk is often devoid of sunspots around solar minimum, the upper atmosphere never rests. The most prominent features approaching the minimum of coronal activity are dense regions overlying mid-latitude boundaries of the large scale magnetic field. Seen above the limb, these features typically give the impression of "ears" (and "jowls"). Samples of these features will be shown, and the relationship to the "extended solar cycle" running from near the poles to the equator over 18 years will be discussed.
