Jupiter Io-B on 7 August, 2011

This was a night-time pass. We used the Icom R-75 HF Receiver tuned to 20.408 MHz (LSB). The antenna was an 8-element log periodic antenna pointed 100 degrees true (no tracking was used). The Jupiter Radio Map immediately below is for reference and shows the orientation of the Io-B enhanced source at the observation time. The Red trace on the Radio SkyPipe chart below shows the bursting at 20.408 MHz (the Blue trace was taken simultaneously at 31.015 MHz but it shows no activity, as expected at the higher frequency). At the time of the chart Jupiter was at azimuth/elevation of approximately 100 degrees true and 21 degrees above the horizon.
