A distinct coronal hole was observed in the final quarter of the last year, (October - December, 2000), at around 180 degrees in the Carrington Longitude. Observed with SXT, the coronal hole had an elongated shape in the north-south direction across the equator, held its outline for at least three rotations (C. R. 1968 - 1970), and broke into three pieces to disappear in January, 2001. In this presentation, we will closely describe the formation through decay of this 'gorgeous' coronal hole, based on a series of SXT images, the synoptic magnetic-field charts given by Kittpeak, and other satellite images taken with TRACE and SoHO. During the October rotation, this hole was in a similar shape to the Italian Peninsula, which reminds us of the famous coronal hole, CH1, observed by Skylab (June - October, 1973). However, it turns out that the 'gorgeous' hole is different from the CH1 in the following two aspects. (1) Although the 'gorgeous' hole appears to connect with the north pole in SXT images, it has a negative polarity, the opposite of the actual polarity of the north pole. Thus, the 'gorgeous' hole is not a polar-hole extension like CH1. (2) The 'gorgeous' hole originated from the active regions that emerged during a few rotations before (around C. R.1965) and rotated at the local rate according to their latitude. This falls into the category of 'sheared extensions' introduced by Wang and Sheeley (1993), not the 'rigid extensions' like CH1.
