A report on the progress of a search for precursors that have direct physical connections to the start of subsequent solar flares is presented. The discussion includes recent results at radio, visible, ultraviolet, and X-ray wavelengths, which are relevant to the preimpulsive (onset) phase. Relationships between various aspects of a theoretical scenario are also established, based on magnetic reconnection with transport-coefficient phase changes, in order to explain flare onset. The pertinent time scales for preimpulsive temporal developments are discussed.
