Science Goal: Dynamics of the bright points in the corona and in the low atmosphere
Program: Fast map, 164x164", 1-side, Q65, no repeat
Target: Active Region
xcen=-762 ycen=76
Instrument: SOTSP
HOP/JOP: 344
Description:
SSC Point of Contact: General: Adam Kobelski, Jessie Duncan (NASA/MSFC) / Tetsuya Watanabe (NAOJ) / Bart De Pontieu (LMSAL), SOT -- Marc DeRosa/Dick Shine (LMSAL), XRT -- Katharine Reeves/Paola Testa (SAO), EIS -- Sarah Matthews/Len Culhane (UCL/MSSL) Main Objective: The objective is to measure the Dopplershifts at different altitudes (temperatures) using a range of emission lines. Scientific Justification: Bright points are ubiquitous: in EMF, in decaying AR, in CHs. With THEMIS we measured large Dopplershifts in Halpha (Karki et al 2025). We would like to study the Dopplershifts in hotter lines with IRIS and EIS, and determine the magnetic configuration with SOT.
