Abstract
The characteristics of charge transfer traps in the WFPC2 are examined and the effect they may have on observations are discussed. The dark tail created just above the location of the trap, as well as any bright tail created in the column above the trap when a bright source is clocked out during the readout, can be modeled as simple exponential decays. Three previously unidentified traps on WF2 are added to the list of "bad pixels". There is no evidence of new traps forming.
