Spatial & Temporal Characteristics of Ha flares during the period 1975-2002 (comparison with SXR flares)
E. Gini, J. Polygiannakis, A. Hillaris +2
Although the energetic phenomena of the Sun (flares, coronal mass injections etc.) exhibit intermittent stochastic behavior in their rate of occurrence, they are well correlated to…
Ten Years of the Solar Radiospectrograph ARTEMIS-IV
C. Caroubalos, C. E. Alissandrakis, A. Hillaris +10
The Solar Radiospectrograph of the University of Athens (ARTEMIS-IV) is in operation at the Thermopylae Satellite Communication Station since 1996. The observations extend from the…
ARTEMIS IV Radio Observations of the 14 July 2000 Large Solar Event
C. Caroubalos, C. E. Alissandrakis, A. Hillaris +13
In this report we present a complex metric burst, associated with the 14 July 2000 major solar event, recorded by the ARTEMIS-IV radio spectrograph at Thermopylae. Additional space…
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…
On signal-noise decomposition of timeseries using the continuous wavelet transform: Application to sunspot index
J. Polygiannakis, P. Preka-Papadema, X. Moussas
We show that the continuous wavelet transform can provide a unique decomposition of a timeseries in to 'signal-like' and 'noise-like' components: From the overall wavelet spectrum…
