CDS wide slit time-series of EUV coronal bright points
2004
Astronomy and Astrophysics
Wide slit (90 × 240 ) movies of four Extreme Ultraviolet coronal bright points (BPs) obtained with the Coronal Diagnostic Spectrometer (CDS) on board the Solar and Heliospheric Observatory (SoHO) have been inspected. The wavelet analysis of the He 584.34 Å, O 629.73 Å and Mg / 368 Å time-series confirms the oscillating nature of the BPs, with periods ranging between 600 and 1100 seconds. In one case we detect periods as short as 236 seconds. We suggest that these oscillations are the
