Requirements for the number of nonthermal electrons which must be accelerated in the impulsive phase of a flare are reviewed. These are uncertain by two orders of magnitude depending on whether hard X-rays above 25 keV are produced primarily by hot thermal electron.,; which contain a small fraction

In a Note Added in Proof in , the statement is made that "As pointed out by Spicer (private communication), estimate [of flare electric fields] is off by four orders of magnitude for his conditions because ... charges move so as to short out most of this field (cf. Drake and Lee, 1977)." As Smith (
