Abstract
We apply local intermittency measure (LIM) analysis to 64 ms time resolved BATSE measurements of hard X-rays from several solar flares. LIM analysis yields information on the character of the processes giving rise to fluctuations in light curves, e.g. avalanche vs. cascade pictures. We present LIM scaleograms for several flares and summarise scaleogram morphological features. More detailed descriptions are given of the behaviour in the flare of 13 January 1992 (the well-known ‘Masuda flare’) and an interesting event on 22 November 1998. All flares display episodes of intermittency across a range of scales. LIM scaleogram features may be consistent with both ‘top-down’ and ‘bottom-up’ scenarios for the development of small-scale structure, sometimes within the same flare. Thus neither class of model captures the totality of the events in a flare.
