PRESENTATION
| Title : | Multiple Cool and Hot Jet Observed by Solar Dynamic Observatory (SDO) |
| Abstract | |
| Multiple Cool and Hot Jet Observed by Solar Dynamic Observatory (SDO) Reetika Joshi and Ramesh Chandra Department of Physics, DSB Campus, Kumaun University, Nainital - 263 002 It is believed that the solar jets and surges are due to the magnetic reconnection processes observed on the solar atmosphere. There dynamics is helpful to understand the large scale solar eruptions. We present here the Ultraviolet (UV) and Extreme Ultraviolet (EUV) observations of solar jets observed on 2017 April 04 using high temporal and spatial resolution AIA data onboard SDO satellite. During the whole day, we have observed several continuous jets and surges form the active region NOAA 12644. Some of the jets were triggered by the nearby failed filament eruptions. While as in some other jets, we observed brightening close to and below the jet site. The evolution indicate this brightening site looks connected to jet site by loops. During the jet activity few of them were observed by the RHESSI in X-rays. The RHESSI analysis indicate the loop-top source, which corresponds to the null-point structures as evidenced by dome like structures visible in AIA EUV images. The multi-band observations evidenced that these jets were triggered due to the magnetic reconnection at low (~ 7 Mm) coronal null point. |
