Geomagnetic disturbances can be monitored by ground-based magnetic observatories recording the three magnetic field components. The global Kp index is obtained as the mean value of the disturbance levels in the two horizontal field components, observed at 13 selected, subauroral stations . ... Geomagnetic activity is the occurrence of K variations. ... But K still remains a local index, describing disturbances in the vicinity of each observatory. ...

... Direct observation of the vortex structure in high- T c superconductors in tilted magnetic fields. Abstract: . A high-resolution Bitter technique has been used to observe an effect of tilting the external magnetic field on the flux line lattice (FLL) in Tl 2 Ba 2 CaCu 2 O 8+x single crystals. ... The reason is believed to be that the formation of the equilibrium vortex state (vortex chains) was prevented by strong pinning, revealed for our crystals by the M(t) curves. ...

... The analysis shows, that asteroid ­ rubble pile loses its fast fragments in no time but the retaining fragments forms a compact structure immersed in dust ­ gas atmosphere, created by interaction of interplanetary medium with dispersed product of collisional evolution of asteroid. By interaction of an asteroid ­ rubble pile with interplanetary medium structures asteroid can increase its brightness on account of blowed up dust simulating phenomenon of distant comet's brightening. ...
