We discovered intense whistler waves with a nose frequency near 80 kHz, a frequency that is not clearly related to the ionospheric magnetic field strength. Here's an image of a rocket . This is the Thunderstorm II rocket launched in 1988 from Wallops Island. These balloons are released 2 hours prior to the T-0 on the associated rocket flights so the balloon will have time to ascend to 30 km altitude. This is an example of a superpressure balloon launch from New Zealand.
Ceiling is reached when the balloon is fully expanded.
Here is the first Hywire apparatus in which a corona ball is being calibrated with a 250kV power supply. Unlike other tethered balloon experiments, only microamps at this voltage are needed for the calibration so the power supply is relatively small. This is a 38,000 cu ft blimp purchased by NASA for the Hywire tethered balloon experiments. This earth gets you back to the U.W. Space Physics Home Page. Back to Atmospheric Electricity .
