Observations of small-scale flux evolution with HINODE
Abstract
We present observations of NOAA 10971 acquired by the Solar Optical Telescope onboard the HINODE satellite. We have inverted spectropolarimetric data of SOT/SP along Fe I doublet at 630.15 nm and 630.25 nm, using the SIR inversion code in order to get magnetic field strength, inclination, azimuth, Doppler velocity and temperature from the observed Stokes profiles. We compare these first results with SOT/FG broad-band observations in the Ca II H line (396.85 ± 0.3 nm) and G-band (430.5 ±± 0.8 nm), and with magnetograms obtained from the narrow-band shuttered Stokes I and V in the wings of the Na I D1 line (589.6 nm). Small-scale events of flux emergence and flux cancellation have been singled out.
