Abstract: We observed the faint meteors on the orbits close to the orbits of Pribram and Neuschwanstein meteorite falls and investigated the possibility that they belong to the stream. Several meteors with low orbital similarity criteria to Pribram and Neuschwanstein meteoroids were found. The atmospheric trajectories and heliocentric orbits of the detected meteors were analyzed to determine whether they are members of the same shower. An orbital evolution model was applied on a certain number of cloned particles to investigate their possible connection with the meteorite stream. Statistical tests were conducted to determine if such small sample of the orbits is similar by chance or if the stream is real. It was found that from the observational as well as the theoretical point of view it is impossible to prove the existence of faint meteor shower connected with the Pribram and Neuschwanstein meteorite stream.

Abstract: We present results of study of interrelation between spatial distribution of the free energy in active regions and the HXR source positions of the flares occurred in these regions. The maps of free energy and currents distribution were rebuilt based on 3D force-free reconstruction with using vector magnetograms by SDO/HMI as input data. We analyzed structure of magnetic energy in pre-flare period on different levels of solar atmosphere. Special attention was focus on areas connected with location of X-ray flare sources on these maps. Obtained results and preliminary conclusions are discussed.
