... As of October 1, 2009, the global rate for the STIS NUV-MAMA dark current has still been occasionally reaching values as high as 13500 counts/s. This high dark current will force use of a signficantly smaller buffer time than would be otherwise needed, and in many cases may push the count rate high enough to make time-tag observations impractical. ... However, we instead found for the NUV MAMA detector an initial global dark rate of between 9000 and 18000 counts/s (a mean of 0.013 counts/s/pixel). ...

As noted earlier Kristian Birkeland, reporting in 1903 on his expeditions to the auroral zone, proposed that magnetic disturbances accompanying the aurora were caused by large electric currents flowing down the length of auroral formations. ... Some scientists disagreed with Birkeland and claimed the electrojets did not connect to space but instead their entire circuit lay inside the ionosphere, like that of other ionospheric currents known at the time, believed to be caused by atmospheric tides. ...
