High resolution observations with Artemis--JLS, (II) Type IV associated intermediate drift bursts
C. Bouratzis, A. Hillaris, C. E. Alissandrakis +5
Aims. We examined the characteristics of isolated intermediate drift bursts (IMDs) and their morphologies on dynamic spectra, in particular the positioning of emission and absorpti…
High resolution observations with Artemis-IV and the NRH. I. Type IV associated narrow-band bursts
C. Bouratzis, A. Hillaris, C. E. Alissandrakis +5
Narrow band bursts appear on dynamic spectra from microwave to decametric frequencies as fine structures with very small duration and bandwidth. They are thought to mark small scal…
Properties of solar energetic particle events inferred from their associated radio emission
A. Kouloumvakos, A. Nindos, E. Valtonen +6
We study selected properties of Solar Energetic Particle (SEP) events as inferred from their associated radio emissions. We used a catalogue of 115 SEP events that consists of entr…
Fine Structure of Metric Type-IV Radio Bursts Observed with the ARTEMIS-IV Radio Spectrograph: Association with Flares and Coronal Mass Ejections
C. Bouratzis, A. Hillaris, C. E. Alissandrakis +5
Fine structures embedded in type-IV burst continua may be used as diagnostics of the magnetic field restructuring and the corresponding energy release associated with the low coron…
Type II and IV radio bursts in the active period October-November 2003
V. Petoussis, P. Tsitsipis, A. Kontogeorgos +7
In this report we present the Type II and IV radio bursts observed and analyzed by the radio spectrograph ARTEMIS IV1, in the 650-20MHz frequency range, during the active period Oc…
Type II Shocks Characteristics: Comparison with associated CMEs and Flares
G. Pothitakis, E. Mitsakou, P. Preka-Papadema +8
A number of metric (100-650 MHz) typeII bursts was recorded by the ARTEMIS-IV radiospectrograph in the 1998-2000 period; the sample includes both CME driven shocks and shocks origi…
Solar flares with and without SOHO/LASCO coronal mass ejections and type II shocks
A. Hillaris, V. Petousis, E. Mitsakou +10
We analyse of a set of radio rich (accompanied by type IV or II bursts) solar flares and their association with SOHO/LASCO Coronal Mass Ejections in the period 1998 2000. The inten…
The improved ARTEMIS IV multichannel solar radio spectrograph of the University of Athens
A. Kontogeorgos, P. Tsitsipis, C. Caroubalos +8
We present the improved solar radio spectrograph of the University of Athens operating at the Thermopylae Satellite Telecommunication Station. Observations now cover the frequency…
Type III events, flares and CMEs, in the extremely active period October-November 2003
E. Mitsakou, M. Thanasa, P. Preka-Papadema +8
The type III observations trace the propagation of energetic electron populations through the Solar Corona which, more often than not, precede or are associated with energy release…
Relation between coronal type II bursts, associated flares and CMEs
George Pothitakis, Panagiota Preka-Papadema, Xenophon Moussas +5
We study a sample of complex events; each includes a coronal type II burst, accompanied by a GOES SXR flare and LASCO CME. The radio bursts were recorded by the ARTEMIS-IV radio sp…
CME on CME Interaction on January 17, 2005
C. Bouratzis, P. Preka-Papadima, X. Moussas +5
On January 17, 2005 a complex radio event associated with an X3.8 SXR flare and two fast Halo CMEs (CME1 & CME2 henceforward) in close succession was observed. We present combined…
