Sounding Rocket CLASP2 Elucidates Solar Magnetic Field up to the Base of the Corona
The team of sounding rocket and balloon experiments in the Solar Science Observatory, NAOJ is engaging in basic experiment and technical development for new techniques of the solar observation to make further understanding of Sun’s phenomena. We aim at
We are developing a new instrument that use a different method than previous ones to measure the chromospheric magnetic field, which is weaker than the magnetic field of the photosphere. Because it is too risky to load a new instrument onto a satellite, we will place it on a sounding rocket or a balloon for observation.
An experiment to measure the magnetic field in the chromatosphere by using ultraviolet light. The CLASP was launched in September 2015, and succeeded in obtaining information
on the chromatosphere magnetic field.
An experiment with refurbished instruments of the CLASP to measure the magnetic field of the chromosphere at different observation wavelengths. the CLASP2 was launched on 11 April 2019 from
the White Sands Missile Test Range in USA, and successfully acquired observational data over a six-minute flight time.
An experiment to continuously observe the Sun with an 1-meter telescope mounted on a balloon flying in the stratosphere. We are developing the SCIP instrument, which measure the chromospheric
magnetic filed in infrared, for the SUNRISE-3 aiming to flight in 2022.
Balloon-borne solar observatory：SUNRISE (in Japanese)
An experiment to observe high-energy coronal plasmas and investigate small-scale energy-release events with the world’s first high-speed X-ray CMOS camera. The FOXSI-3 was launched and
succeeded in focusing imaging spectroscopic observation of the solar corona on September 7, 2018!
