Internetwork chromospheric bright grains observed with IRIS
Juan Martínez-Sykora, Luc Rouppe van der Voort, Mats Carlsson +18
The Interface Region Imaging Spectrograph (IRIS) reveals small-scale rapid brightenings in the form of bright grains all over coronal holes and the quiet sun. These bright grains a…
The Unresolved Fine Structure Resolved - IRIS observations of the Solar Transition Region
V. Hansteen, B. De Pontieu, M. Carlsson +18
The heating of the outer solar atmospheric layers, i.e., the transition region and corona, to high temperatures is a long standing problem in solar (and stellar) physics. Solutions…
An Interface Region Imaging Spectrograph first view on Solar Spicules
T. M. D. Pereira, B. De Pontieu, M. Carlsson +17
Solar spicules have eluded modelers and observers for decades. Since the discovery of the more energetic type II, spicules have become a heated topic but their contribution to the…
The Association of Solar Flares with Coronal Mass Ejections During the Extended Solar Minimum
N. V. Nitta, M. J. Aschwanden, S. L. Freeland +3
We study the association of solar flares with coronal mass ejections (CMEs) during the deep, extended solar minimum of 2007-2009, using extreme-ultraviolet (EUV) and white-light (c…
Soft X-ray Fluxes of Major Flares Far Behind the Limb as Estimated Using STEREO EUV Images
N. V. Nitta, M. J. Aschwanden, P. F. Boerner +3
With increasing solar activity since 2010, many flares from the backside of the Sun have been observed by the Extreme Ultraviolet Imager (EUVI) on either of the twin STEREO spacecr…
First 3D Reconstructions of Coronal Loops with the STEREO A+B Spacecraft: IV. Magnetic Modeling with Twisted Force-Free Fields
Markus J. Aschwanden, Jean-Pierre Wuelser, Nariaki V. Nitta +3
The three-dimensional (3D) coordinates of stereoscopically triangulated loops provide strong constraints for magnetic field models of active regions in the solar corona. Here we us…
Solar Stereoscopy with STEREO/EUVI A and B spacecraft from small (6 deg) to large (170 deg) spacecraft separation angles
Markus J. Aschwanden, Jean-Pierre Wülser, Nariaki Nitta +1
We performed for the first time stereoscopic triangulation of coronal loops in active regions over the entire range of spacecraft separation angles ($α_{sep}\approx 6^\circ, 43^\ci…
Fast Time Structure During Transient Microwave Brightenings: Evidence for Nonthermal Processes
N. Gopalswamy, J. Zhang, M. R. Kundu +2
Transient microwave brightenings (TMBs) are small-scale energy releases from the periphery of sunspot umbrae, with a flux density two orders of magnitude smaller than that from a t…
