Observations 2023-12-27 20:30-22:30 UTC

This time was chosen because of a good chance to see DAM signals from both hemispheres of Jupiter, so that that could be calibration relative to each other. We observed with NenuFAR, KAIRA, GLOW (DE601,602,603,604,605,609, but DE601 had strong noise and dropped out too early), the LWA (LWA1, LWA-SV), and other international LOFAR stations ().

All LOFAR(-like) stations observed in RCU mode 3 (band 10_90) with 8-bit recording of 244 subbands (40-283, 8-55 MHz). Beamforming was done in direction 0.5826639,0.2118205,J2000 or 0,0,JUPITER.

Here are beamlet statistics (dynamic spectrum) just before the observations:

This plot was taken from the realtime display at https://www.sgo.fi/KAIRA/bst.php. It shows a nice Io-B arc (north).

Beamlet statistics (dynamic spectra for XX and YY) from NenuFAR show the great performance of this telescope:

These plots show the strong Io-B arc, but unfortunately not the Io-D counterpart from the southern hemisphere that we had hoped for. However, the signal is clearly strong enough for a VLBI analysis.

The LWA participated with the stations LWA1 and LWA-SV with director's time in project DW005. The schedule file DW005_231227_2230_0001.idf was used.
