Magnetic flux emergence in quiet sun internetwork regions has been drawing attention due to recent progress in high-resolution observations. The launch of Hinode, and specifically the SP instrument, has allowed observers to detect the rising of hG horizontal magnetic loops in quiet Sun regions with no preexisting flux. Our aim is to observe both quiet Sun internetwork regions and active regions for magnetic flux emergence. We plan to follow the rising flux from its eruption through the photosphere and into the chromosphere, measuring the delay between the first manifestations of flux eruption in the photosphere until its effects on the chromospheric layers are visible. For this we aim at coordinating simultaneous observations from the SP instrument on board Hinode and the new CRISP spectropolarimeter recently installed on the Swedish 1-m Solar Telescope in La Palma. The objective is to combine CRISP's higher resolution, higher cadence and ability to measure full Stokes parameters in both the photosphere and chromosphere with SP's seeing-free and well-calibrated observations. Having simultaneous observations with both instruments will allow to calibrate the CRISP instrument and checking the sanity of its measurements. In addition, and if possible, we would like to observe with EIS to see if any larger scale changes in the transition region and coronal magnetic field configuration is evident as a result of emergence. |
