Abstract

Preliminary results of polarization measurements at three solar flares of July 5 and 6, 1974, are given. The measurements were performed at hν ≈ 15 keV with Thomson-scattering polarimeter on the ‘Intercosmos 11’ satellite.

At the decay phase of the flare on July 5 we obtained P = 3.4–5.0%, which did not exclude some contribution from non-thermal processes. At the flares of July 6 we found P =1.0–1.9% and P = 0.1–2.0%, respectively: neither value exceeds the level of statistical fluctuations.
