... Aurora from Space . ... Magnetic Storms . ... The "ring of fire" seen by satellite cameras around the polar caps (picture below) is probably created by electrons leaking from the tail's plasma sheet, whose magnetic field lines form a somewhat imperfect trap. ... One possible explanation involves the close association between auroral arcs and electric currents which flow along field lines between the ionosphere and distant space ( Birkeland currents ). ... Why no aurora at the magnetic poles? ...

Figure 6. The squares show the telescope defocus data from August 15 (Figure 5) plotted as a function of time. For the defocus data the y-axis is in units of ?m. The circles show the telescope altitude in degrees as a function of time. As expected from the good linear correlation seen in Figure 5, the data very much look like they are driven by altitude changes. ... Second, notice that the defocus data consists of pairs of points which were taken at nearly the same telescope altitude. ...

Abstract: The calculation of flux upper limits in the source-free ("background") regions of photon-limited images is complicated by instrumental and statistical modeling and requires non-trivial computational effort. ... The principal component in this is the time taken to pre-process and handle the 30 GB of RASS data rather than the calculation of each upper limit. ...

... The firmware (built-in software) in the NexStar 8 GPS and 11 GPS scopes is designed to be updated by downloading a file from Celestron and uploading it from your PC to your scope.  ... To upload the firmware, you need a cable to connect from the serial port on your computer to the PC port on the base of the scope.  The PC port on the base of the scope is a standard RJ-45, so it is fairly easy to build a cable using a flat RJ-45 cable and a DB-9 (female) to RJ-45 adapter.  ...
