Abstract
A large number of synoptic maps from a variety of instruments are used to s how the general morphology of the Sun at the time of the First Whole Sun Mo nth Campaign. The campaign was conducted from August 10 to September 8, 199 6. The synoptic maps cover the period from Carrington rotation 1912/253 deg rees to Carrington rotation 1913/45 degrees. The synoptic maps encompass bo th on-disk data and limb data from several heights in the solar atmosphere. The maps are used to illustrate which wavelengths and data sets show parti cular features, such as active regions and coronal holes. Of particular int erest is the equatorial coronal hole known as the "elephant's trunk," which is clearly evident in the synoptic maps of on-disk data. The elephant's tr unk is similar in appearance to the Shylab-era, "Boot of Italy," equatorial coronal hole. The general appearance of the limb maps is explained as well . The limb maps also show evidence for equatorial coronal holes.
