Popis: The effect of chromospheric flares at the end of the exposure has been studied for all radiochemical facilities measuring the flux of solar neutrino. For chlorine-argon measurements (Brookheaven), it has been found that the development of flared results in the count rate acceleration to 4.7 ± 1.2 SNU. The effect of this growth is fictitious; this is an increase in the effectiveness of reaction product extraction from the target matter under the action of the ULF electromagnetic disturbance induced by the flare X-rays rather than an increase in the flux. The indications that a similar effect is present in the SAGE gallium-germanium measurement have been obtained. For the GALLEX gallium-germanium experiment, the effect of flares has not been found; the sign of this effect possibly differs from that of the Brookheaven and SAGE measurements. The found difference agrees with the conclusion that the results of the SAGE and GALLEX measurements anticorrelate for the exposures that end simultaneously.
