We have studied the magnetic helicity transport rate and the current helicity for solar active region (AR) NOAA 10488 and find a complex relationship between them. We further extend this study to a statistical one, and find that 33 among the selected 57 ARs show opposite sign for the two parameter.To search for other articles by the author(s) go to: http://adsabs.harvard.edu/abstract_service.html
