Connecting the Dots: FOXSI-3 Data Points add up to Unprecedented Image of Solar Corona
Oct. 17, 2018
FOXSI-3 succeeded in focusing imaging spectroscopic observation in soft X-rays!!

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 contribute the CLASP, CLASP2, and FOXSI-3 sounding rocket experiments and the SUNRISE-3 balloon-borne solar observatory.

Measurement of Magnetic Fields in the Solar Chromosphere

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.

CLASP Sounding Rocket Experiment: Succeeded in observation of the chromatospheric magnetic field!

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.

[Grant-in-Aid for Scientific Research(S)] Approach to understand the solar coronal and chromospheric heating -from Hinode, IRIS & CLASP to SOLAR-C

CLASP2 Sounding Rocket Experiment

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.

SUNRISE-3 Balloon-borne Solar Observatory

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)

Observation of the Energetic Solar Corona

FOXSI-3 Sounding Rocket Experiment

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!
