Description:
The Chromospheric Lyman-Alpha Spectro-Polarimeter (CLASP) sounding rocket is a high precision spectro-polarimeter designed to measure the Lyman-alpha Stokes profiles (I, Q, and U), and aims at inferring the magnetic field vector of the upper chromosphere and the transition region. CLASP team requests observing support from Hinode and IRIS to uncover the magnetic structure and dynamical state from the photosphere to the corona. The launch date is scheduled for Sept. 3, 2015, and the current launch window is 17:16 - 18:16 UT. The CLASP will avoid the time periods when both Hinode and IRIS pass though the SAA, and the resulting launch window is tentatively 17:30 - 18:15 UT based on the current SAA prediction (this will be updated based on new orbit information before the launch). The flight time is about 5 minutes. The target will be a quiet region near the solar limb. The 400-arcsec-long slit is set to perpendicular to the solar limb. The exact coordinates and the launch time will be informed before the planning.
