Observational evidence for shocks in the solar photosphere - Hinode 
SOT/SP data promise

ABSTRAKT / ABSTRACT :

High-resolution spectroscopic observations recently acquired with novel
spectropolarimeter (SP) at the 50cm Solar Optical Telescope (SOT) onboard
the Hinode satellite are used to test whether they can serve for 
determination
of the observational evidence for shocks in the solar photosphere.

Time series of spectropolarimetric 2D data of the Fe I 630.1 nm spectral 
line
profile at different centre-to-limb positions are investigated in a 
statistical
sense only for the non-magnetic part of the solar photosphere but over 
the whole
north-south meridian scan performed by the SP instrument in ~1.5 days 
with the
spatial resolution of only 0.18 arcsec.

At the actual spatial resolution of the SOT/SP these data show to be of the
absolutely best quality for the future statistical comparison to the 
synthetic
spectral profiles derived using the numerical simulation of the solar 
convection.
