Query: Synoptic solar observations of the Solar Flare Telescope focusing on
  space weather   The solar group at the National Astronomical Observatory of Japan is
conducting synoptic solar observations with the Solar Flare Telescope. While it
is a part of a long-term solar monitoring, contributing to the study of solar
dynamo governing solar activity cycles, it is also an attempt at contributing
to space weather research. The observations include imaging with filters for
H$\alpha$, Ca K, G-band, and continuum, and spectropolarimetry at the
wavelength bands including the He I 1083.0 nm / Si I 1082.7 nm and the Fe I
1564.8 nm lines. Data for the brightness, Doppler signal, and magnetic field
information of the photosphere and the chromosphere are obtained. In addition
to monitoring dynamic phenomena like flares and filament eruptions, we can
track the evolution of the magnetic fields that drive them on the basis of
these data. Furthermore, the magnetic field in solar filaments, which develops
into a part of the interplanetary magnetic cloud after their eruption and
occasionally hits the Earth, can be inferred in its pre-eruption configuration.
Such observations beyond mere classical monitoring of the Sun will hereafter
become crucially important from the viewpoint of the prediction of space
weather phenomena. The current synoptic observations with the Solar Flare
Telescope is considered to be a pioneering one for future synoptic observations
of the Sun with advanced instruments.
