Flux tube on the sun may carry linear and torsional Alfven waves generated by photospheric motion. Photospheric motion of 2 km/s would provide magnetic fluctuation of 40G for 1KG tube and for the Alfven speed of 50km/s. This may be close to the detection limit of the Stokes Q and U signals for flux tubes located in the sun center. However, for flux tubes located near the limb, the fluctuation would be seen in the Stokes V signal, and can be detectable.
We also may be able to confirm the 90 degree phase shift between magnetic fluctuation and velocity fluctuation, which is easier to observe for flux tubes near the limb. Detection of waves would be important in terms of coronal heating and solar wind acceleration. An attempt to detect waves along flux tubes will be reported.
