New imaging system for solar eruptions at Hida Observatory (2016/05/07)
Solar Dynamics Doppler Imager(SDDI) was installed on SMART in the end of 2016-Apr to observe the motion of filaments eruptions.
In contrast to the previous observing system, which was able to observe the velocity of filament eruptions up to 60km/sec, the new system can capture the velocity up to 400km/sec.
Soon after (~1week) the installation of the instrument on SMART, we successfully observed a filament activation that moved with a speed of ~200km/sec on May 4th.

Today's Sun

From now, SDDI will perform regular observation of the sun, and the relation between the motion of filament eruptions and the occurrence of Coronal Mass Ejections (CMEs) that affect the space environment of the earth will be investigated.

Prominence Eruption (2013/5/31 & 6/1)
Over the space of two days, from 2013/5/31 to 6/1 (JST), a prominence eruption was observed above the west limb of the Sun. Movie (Javascript) of the observations using the SMART telescope at Hida Observatory
(1) 2013/5/31 (2) 2013/6/1
The top of the image is celestial north and the right of the image is west. The time shown is in UT. The movie was made from images taken by the full-disk imaging telescope (T1) where the target region has been cut out.

Flare (2012/8/18)
On 2012/8/18 a M5.5 flare was observed. At this time, students from Kyoto prefectural Rakuto High School were visiting Kwasan Observatory to practice solar observations. Because of this, we were able to observe the flare spectra.
