The TEX instrument observed a medium-scale density structure in the dawnside plasmasphere during a quiet period (1 2 June 2008).
When the CAPS-ELS feature was observed, the RPWS instrument observed an intense plasma wave feature near 2 kHz, with no magnetic component above the instrument threshold.
The STEREO instruments observed the July 23 , 2012extreme SEP event, which has been extensively studied in comparison with the Carrington 1859 eruption.
In this method, the surgeon does not operate a surgery with the hands viewing directly the effect of his/her actions, but through instruments, observing the scene on a monitor.
At roughly 02 18 UTC, approximately 6 min (∼2233 km, 16.79 Hyperion radii) before the closest approach, the CAPS-ELS instrument observed more than an order-of-magnitude increase in the 160 280 eV differential energy flux in two sharp peaks.
With a 2.4 m mirror, Hubble's four main instruments observe in the near ultraviolet, visible, and near infrared spectra.
More recently, Rowson et al 24 analysed head impacts measured using instrumented helmets and observed a 50% likelihood of concussion associated with a resultant angular acceleration of 6383 rad/s and resultant angular velocity of 28.3 rad/s.
Ph.D. theses generally involve building sensitive receivers and instruments, observing the cosmos from the ground, balloons, or satellites, analyzing data from those observations, or some combinations of these.
Sensitive to 13 bands of light, the instruments will observe a range of properties in the things they see, allowing for example the distinction to be made between different types of crops and for an assessment to be made about their health.
The instrument observed the resulting spark through a telescope; the component colours would have told scientists which atomic elements were present.
