Narrow-band bursts (spikes) are very small duration and bandwidth bursts which appear on dynamic spectra from microwave to decametric frequencies; they are believed to be manifestations of small scale energy release through magnetic reconnection. Here we present the results of a study of the characteristics of spike-like structures detected near the front of type-II bursts. We used high...
We present the results from the finalized two comprehensive catalogs of solar energetic electron events and their related radio emissions. The solar energetic electron events are detected by the ACE/EPAM instrument covering solar cycles (SC) 23 & 24 in the two energy channels, 103-175 keV and 175-315 keV. The related radio emission signature catalog represents the interplanetary radio...
It is well known that not all solar flares are connected with eruptions followed by coronal mass ejection (CME). Even strongest X-class flares may not be accompanied by eruptions or are accompanied by failed eruptions. One of important factor that prevent eruption from developing into CME is strength of the magnetic field overlying flare site. However, few other factors should be considered...
Solar coronal cavities are dark structures with a rarefied density compared with surrounding streamers. They are often observed as a component of the classic three-part structure of a coronal mass ejections (CME), quiescent cavities are observed mostly in the polar crown regions and may be long-lived. Some of the quiescent cavities may finally erupt as a CME.
We present multi-wavelength...
We present four cases of quasi-periodic pulsations (QPPs)
of microwave emission from solar active regions (ARs) on pre-flare phase.
We used the Nobeyama Radioheliograph (NoRH) and
Nobeyama Radio Polarimeters (NoRP) daily observations.
We computed the time series of maximum brightness temperature
and total flux over selected field-of-view (FOV) in three cases and total solar flux in...
