[en] A number of suggestive coincidences are found in a purely speculative analogy between the by-products of a minihole fast evaporation in a plasma, and by-products from flares at magnetospheres. Solar flares might serve as good examples. From an observational point of view attention is drawn to the considerable extent of the 'blank' time interval existing between known 'before' and 'after' evidences on flares, during which some exotic energy conversion processes could be invoked to explain the large amount of energy released in time-scales that might be very short. It is suggested that fundamental progress in the knowledge of energy conversion processes in flares require observational data with a time resolution several orders of magnitude better than the currently availble data, particularly for hard X-rays.
