Active region upflows in various coronal structures and their coupling to the lower atmosphere
Yingjie Zhu, Louise Harra, Krzysztof Barczynski +13
Plasma upflows with a Doppler shift exceeding -10 km/s at active region (AR) boundaries are considered potential sources of the nascent slow solar wind. We investigate the driving…

Anomalous cross-field motions of solar coronal loops
Sudip Mandal, Hardi Peter, James A. Klimchuk +1
Here, we present several examples of unusual evolutionary patterns in solar coronal loops that resemble cross-field drift motions. These loops were simultaneously observed from two…

Stereoscopic observations reveal coherent morphology and evolution of solar coronal loops
B. Ram, L. P. Chitta, S. Mandal +2
Coronal loops generally trace magnetic lines of force in the upper solar atmosphere. Understanding the loop morphology and its temporal evolution has implications for coronal heati…
