✦ Synopsis

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 (private communication) has acknowledged, this assertion is incorrect, since the cited effect does not occur in collisional solar conditions [vc/yk >> (pJAk) 3/2=-R 3/2 in the notation of Equation ( ) and Figures and of Drake and Lee (1977)].

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
