Abstract:
We present the investigation of 11 recurring solar jets that originated from two
different sites (site 1 and site 2) close to each other (≈11 Mm) in NOAA active region
(AR) 12035 during 15 – 16 April 2014. The jets were observed by the Atmospheric Imaging
Assembly (AIA) telescope on board the Solar Dynamics Observatory (SDO) satellite. Two
jets were observed by the telescope of the Aryabhatta Research Institute of Observational
Sciences (ARIES), Nainital, India, in Hα. On 15 April, flux emergence is strong in site 1,
while on 16 April, flux emergence and cancellation mechanisms are involved in both sites.
The jets of both sites have parallel trajectories and move to the south with a speed between
100 and 360 km s−1. The jets of site 2 occurred during the second day have a tendency to
move toward the jets of site 1 and merge with them. We conjecture that the slippage of the
jets could be explained by the complex topology of the region, which included a few lowaltitude null points and many quasi-separatrix layers (QSLs), which could intersect with one
another.
