AB: An analysis of SOHO LASCO C2 images over 1996-2005 defines the years and latitudes at which bright, white light coronal structures are most persistent from rotation to rotation. In the northern hemisphere, these features are most notable for the years 2002-2003 and the latitudes 40-60 degrees. This time interval overlaps that of a north pole passage of Ulysses. As Ulysses passes overhead, solar rotation sweeps the interplanetary extensions of these persistent coronal features over the spacecraft, thereby revealing the interplanetary effects of very bright and recurrent K-corona at high solar latitudes.
