Jet 2: 2010 September 17 – Left panel: AIA 171 Å image of the jet observed on 2010 September 17. The jet appeared to evolve from the edge of the active region, 11106 (S20 W09), which was associated with a positive-polarity sunspot with anemone magnetic topology. A small-scale brightening was observed at the jet footpoint before the jet evolution and the jet evolved as a simple spire. The jet started its activity at 00:15 UT and lasted until 00:31 UT. Middle panel and right panel: the LOS HMI magnetogram image at 23:29 UT, before the jet evolution and at 00:22 UT, during the jet, respectively. The emergence of positive-polarity near the negative-polarity region is shown by white arrows. Later on, the small negative flux region cancelled with emerging positive-polarity. This magnetic activity lasted for a few hours and was co-temporal and co-spatial with the jet activity.
