Occasionally there are features in the data which are not regularly seen and are likely not of astrophysical origin.  These include rare events on the spacecraft or detectors.  In this section, we discuss those that have been brought to our attention and our current understanding of their causes.  If you have seen something unexplained in your dataset, please let us know.
