This is the most modern solar telescope in the Mitaka campus.
Solar flares are violent explosions taking place in the solar corona.
Strong magnetic fields of solar active regions, reaching far out into the corona, are sometimes distorted by the motion of gas on the solar surface. These telescopes observe magnetic fields , velocity fields , sunspot structures , and flares in H-alpha light . Observations are all performed automatically under computer control. The image data are stored in video laser disks. This is the most advanced and automated observing system in the world.
