| Abstract: |
Recent observations of sunspot light-bridges (LBs) have shed new light on the fact that they are often
associated with significant chromospheric activity. In particular chromospheric jets (Shimizu et al. 2009)
persisting over a period of days have been identified, sometimes associated with large downflows at the
photospheric level (Louis et al. 2009). One possible explanation for this activity is reconnection low
in the atmosphere. LBs have also been associated with a constant brightness enhancement in the
1600 Å passband of TRACE, and the heating of 1 MK loops. Using data from EIS, SOT and STEREO EUVI we
investigate the response of the transition region and lower corona to the presence of a LB. |
