SOTSP: HOP331 test (AR12626)
2017-01-17T11:40:00 to 2017-01-17T12:40:00
Science Goal: Flux cancellation and magnetic flux rope formation
Program: HOP331, 60"x120" fast map, repeats
Target: Active Region
xcen=-421 ycen=180
Instrument: SOTSP
HOP/JOP: 331
Description:
The aim of this IHOP is to make repeated observations of the likely sites of flux cancellation along the PIL of the target active region as it crosses the solar disk. 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.
