Multiscale analysis of active region evolution by Hewett, R, Gallagher, P, McAteer, R, Young, C, Ireland, J, Conlon, P, Maguire, K

“…Here, a continuous wavelet technique is developed, analyzed, and used to investigate the multiscale structure of an evolving active region using magnetograms obtained by the Michelson Doppler Imager (MDI) onboard the Solar and Heliospheric Observatory (SOHO). The multiscale structure was measured using a 2D continuous wavelet technique to extract the energy spectrum of the region over the time scale of 13 days. …”

Multifractal properties of evolving active regions by Conlon, P, Gallagher, P, McAteer, R, Ireland, J, Young, C, Kestener, P, Hewett, R, Maguire, K

“…Here we explore the multiscale properties of a number of evolving active regions using magnetograms from the Michelson Doppler Imager (MDI) on the Solar and Heliospheric Observatory (SOHO). The multifractal spectrum was obtained by using a modified box-counting method to study the relationship between magnetic-field multifractality and region evolution and activity. …”

Searches for high-frequency variations in the 8B solar neutrino flux at the sudbury neutrino observatory by Aharmim, B, Ahmed, SN, Anthony, A, Barros, N, Beier, E, Bellerive, A, Beltran, B, Bergevin, M, Biller, S, Boudjemline, K, Boulay, MG, Burritt, T, Cai, B, Chan, Y, Chauhan, D, Chen, M, Cleveland, B, Cox, G, Dai, X, Deng, H, Detwiler, J, Dimarco, M, Doe, P, Doucas, G, Drouin, P

“…The second search focused on regions in which g-mode signals have been claimed by experiments aboard the Solar and Heliospheric Observatory satellite, and was sensitive to signals with amplitudes of 10% or greater. …”

Photon scattering in the solar ultraviolet lines of HeI and HeII by Jordan, C, Smith, G, Houdebine, E

“…Observations made with the Coronal Diagnostic Spectrometer (CDS) onboard the Solar and Heliospheric Observatory (SOHO) are used to investigate the behaviour of the intensities of the emission lines of He I, He II and O III at the quiet Sun-centre and at θ = 60° towards the equatorial limb. …”

The anomalous intensities of helium lines in a coronal hole by Jordan, C, Macpherson, K, Smith, G

“…Observations made at the quiet Sun-centre with the Coronal Diagnostic Spectrometer (CDS) and Solar Ultraviolet Measurements of Emitted Radiation (SUMER) instruments on the Solar and Heliospheric Observatory (SOHO) have shown that the intensities of the resonance lines of He I and He II are significantly larger than predicted by emission measure distributions found from other transition region lines. …”
