When solar flares occur, wave-like disturbances and shock waves are sometimes observed in several kinds of wavelengths. Last December, the X-ray telescope (XRT) on board Hinode detected the wavelike disturbance associated with a large flare. The speed of this wavelike disturbance is about 630 km/s. In this flare, a type II radio burst, which shows the existence of a shock wave, was also observed with the Hiraiso Radio Spectrograph (HiRAS). Moreover, EUV Imaging Spectrometer (EIS) on board Hinode scanned the region where the X-ray wavelike disturbance was propagated. We analyzed these data and examine whether the wavelike disturbance is shock wave or not.
On the other hand, in this May, the XRT detected a slowly and widely propagating wave, just like the EIT waves.
In this meeting, we will show the analysis results. |
