We thank Dr. Karen Harvey and Dr. Frank Recely for producing the daily coronal hole maps, and Dr. Jack Harvey for providing the BBSO data. After the Kitt Peak observations, we use He I 1083A images from Mauna Loa Solar Observatory. We also thank the ACE SWEPAM (Solar Wind Electron, Proton, and Alpha Monitor) instrument team and the ACE Science Center for providing the ACE data. Dr. Bill Cheng developed tgif software, which has been used to make this page.

*The Bartels Calendar

J. Bartels defined his calendar based on observations of daily geomagnetic activity. Over long periods the geomagnetic recurrence rate is very close to 27 days. (The equatorial rotation rate of the Sun is also close to 27 days.) Rotation 1 Day 1 in this sequence was assigned arbitrarily by J. Bartels to February 8, 1832. For reference, Bartels rotation 2270 started on November 2, 1999, at 00:00:00 UT. (After ACE web page)
