Multi-Wavelength Analysis of the 29 September 2002 M2.6/2N Flare
Dzifčáková, Elena; Karlický, Marian; Kulinová, Alena +1 more
Using TRACE EUV 171 Å line, Hα line, Zürich radio, RHESSI, and HXRS observations the 29 September 2002 flare (M2.6), which occurred in AR NOAA 0134, was analyzed. Flaring structures were compared with a potential magnetic field model (field lines and quasi-separatrix layers) made from SOHO/MDI full-disk magnetogram. Series of high-resolution SOHO/…
Observations of CME-related phenomena in a wide spectral range
Grechnev, V. V.; Uralov, A. M.; Borovik, V. N. +7 more
We study pre-eruptive, eruptive, and post-eruptive phenomena related to a CME that occurred on November 23, 2000 by means of joint analyses of data from various spectral ranges. Almost all known CME-associated phenomena were observed during this event, i.e., a filament eruption, solar flare, dimmings, and a post-eruptive arcade formation. Followin…
Re-Evaluation of the Flare Type II CME Association
Kim, Y. -H.; Moon, Y. -J.; Shanmugaraju, A. +2 more
We have re-evaluated the association of type II solar radio bursts with flares and/or coronal mass ejections (CMEs) using the year 2000 solar maximum data. For this, we consider 52 type II events whose associations with flares or CMEs were absent or not clearly identified and reported. These events are classified as follows; group I: 11 type IIs f…
A comparison of the use of genetic and hill-climbing algorithms to fit low-l solar p-mode spectra
Chaplin, W. J.; Elsworth, Y.; Fletcher, S. T.
We present a comparative study of low-l solar p-mode parameters extracted by genetic-algorithm and `standard' hill-climbing minimisation routines. To effect this we make use of observations made in integrated sunlight by the Birmingham Solar-Oscillations Network (BiSON) and the GOLF instrument on board the ESA/NASA SOHO satellite, in addition to a…
