The Chromospheric Lyman-Alpha Spectro-Polarimeter (CLASP) is a sounding rocket experiment to observe the Sun through Lyman-alpha line emissions. CLASP was successfully launched to space from White Sands in the U.S.A. at 11:01 am local time on September 3.

CLASP aims to infer the nature of the magnetic fields in the chromosphere and the transition region of the Sun. The CLASP project has been carried-out through international collaboration between the U.S.A., Spain, France, Norway and Japan. The CLASP flight instrument was assembled in the Advanced Technology Center (ATC) of the National Astronomical Observatory of Japan (NAOJ).

All the data stored in the instrument during the flight were recovered successfully. Analyzing the observational data precisely, we will obtain information about the magnetic field of the solar chromosphere.
