| We discovered three successive
Moreton waves generated by a single solar flare. These waves
were observed on 3 August 2005 with
Solar Magnetic Activity Research Telescope (SMART) at Hida Observatory
of Kyoto University. Movie of three successive
Moreton waves

three
successive Moreton wave
This movie shows the three successive Moreton waves observed in "Dopplergrams".
"Dopplergrams" is created using the equation of
log (I_blue / I_red), where I_red and I_blue are the intensity almost simultaneously
observed in red and blue wing (H-alpha +/- 0.5 angstrom), respectively.
This method makes the line-of-sight motion clear.
The wave fronts of Moreton waves are marked by pluses in the right panel
(red pluses: 1st wave, green pluses: 2nd wave, blue pluses: 3rd wave).

Original and Running difference in H-alpha center and
wings
Each movie has two panels. Left panel shows the original
data observed with SMART. Right panel is the "running difference" image,
which are made by subtracting the previous image from the original one.
The running difference method makes the moving feature clear.
