Active-Region Tilt Angles from White-Light Images and Magnetograms: The Role of Magnetic Tongues
M. Poisson, P. Démoulin, C. H. Mandrini +1
The presence of elongations in active region (AR) polarities, called magnetic tongues, are mostly visible during their emergence phase. AR tilts have been measured thoroughly using…
Correcting the effect of magnetic tongues on the tilt angle of bipolar active regions
M. Poisson, M. C. López Fuentes, C. H. Mandrini +2
The magnetic polarities of bipolar active regions (ARs) exhibit elongations in line-of-sight magnetograms during their emergence. These elongations are referred to as magnetic tong…
Two successive partial mini-filament confined ejections
M. Poisson, C. Bustos, M. López Fuentes +2
Active region (AR) NOAA 11476 produced a series of confined plasma ejections, mostly accompanied by flares of X-ray class M, from 08 to 10 May 2012. The structure and evolution of…
Evidence of Twisted flux-tube Emergence in Active Regions
Mariano Poisson, Cristina H. Mandrini, Pascal Démoulin +1
Elongated magnetic polarities are observed during the emergence phase of bipolar active regions (ARs). These extended features, called magnetic tongues, are interpreted as a conseq…
