These mosaics have a common area of $7\sp\prime52\sp{\prime\prime} \times 9\sp\prime25\sp{\prime\prime}$ which is the largest area of the Orion Nebula covered by the Hubble Space Telescope images in a single study. Making use of these Wide Field Planetary Camera 2 data, a survey of compact sources and stars down to V $\approx$ 22 has been done. A total of 489 sources that are not Herbig-Haro objects have been found. 145 of them can be classified as protoplanetary disks (proplyds). The proplyds have been classified into eight different forms. The forms which show strong evidence of interaction with a stellar force are concentrated near $\Theta\sp1$C Ori. Those forms that do not show such evidence are more widely spread.65 p.application/pdfengCopyright is held by the author, unless otherwise indicated.
