Abstract

We present a formation process of a filament in active region NOAA 12574 during the period from 2016 August 11 to 12. Combining the observations of the Global Oscillation Network Group Ha, the Hida spectrum, and the Solar Dynamics Observatory/AIA 304 angstrom, the formation process of the filament is studied. It is found that cool material (T similar to 10(4) K) is ejected by a series of jets originating from the western footpoint of the filament. Simultaneously, the magnetic flux emerged from the photosphere in the vicinity of the western footpoint of the filament. These observations suggest that cool material in the low atmosphere can be directly injected into the upper atmosphere and the jets are triggered by the magnetic reconnection between pre-existing magnetic fields and new emerging magnetic fields. A detailed study of a jet at 18:02 UT on August 11 with GST/BBSO TiO observations revealed that some dark threads appeared in the vicinity of the western footpoint after the jet and the projection velocity of plasma along the filament axis was about 162.6 +/- 5.4 km s(-1). Using these observations of the Domeless Solar Telescope/Hida, we find that the injected plasma by a jet at 00:42 UT on August 12 was rotating. Therefore, we conclude that the jets not only supplied the material for the filament, but also injected the helicity into the filament simultaneously. Comparing the quantity of mass injection by the jets with the mass of the filament, we conclude that the estimated mass loading by the jets is sufficient to account for the mass in the filament.
