We request combined IRIS, EIS, and XRT observations. IRIS studies with chromospheric and transition region lines will allow us to determine the locations and possible heights of reconnection occurring as a consequence of flux cancellation. Large FOV EIS observations will provide abundance measurements along the PIL and throughout the active region. XRT observations will be used to investigate the presence of a sigmoid/flux rope.
