These two elements, part of a group called the rare-earth metals, have unusual configurations of electrons orbiting their nuclei, and thus unusually powerful magnetic properties.
Observations of unusually large magnetic fields in the ionosphere indicate periods of maximum stress on Titan's ionosphere and potentially of the strongest loss rates of ionospheric plasma.
HD 166435 may have unusually stable magnetic fields, which would keep spots at fixed locations for years, the team speculates in a report accepted for publication in the journal Astronomy and Astrophysics.
After two or more days of an unusually calm magnetic field -- and (presumably) higher melatonin -- his dreams were much more vivid and bizarre than they were following stormier phases (when melatonin may have been suppressed).
Unlike some unusually dense, strongly magnetic, or electrically conductive mineral deposits, the target fluids within geothermal systems are not known to generate a specific geophysical anomaly that is measureable at the surface.
In contrast to the uniform far-field wave, the electric and magnetic fields behave unusually in the near-field.
However, the solar magnetic field was unusually weak around this last solar minimum (2009), which resulted in a record-high GCR flux (Mewaldt et al. 2010).
Led by Delores Knipp, a space weather expert at the University of Colorado at Boulder, the study suggests that an unusually intense solar storm activated magnetic sensors in the undersea destructor mines, causing them to blow up en masse.
HP 129Xe displays a reasonably high Ostwald solubility in many tissues [12], including the blood (∼14%), and exhibits an unusually large, environmentally dependent nuclear magnetic resonance (NMR) chemical shift range (>200 ppm in vivo) that allows dissolved 129Xe to be excited and detected separately from gas-phase 129Xe [8].
But even for this phase it has been unusually quiet, with little roiling of the magnetic fields that induce sunspots.
