| - | 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 (FIXME). | + | This time was chosen because of a good chance to see DAM signals from both hemispheres of Jupiter, so that they can be calibrated relative to each other. We observed with NenuFAR, the LWA (LWA1, LWA-SV), KAIRA, and a number of LOFAR stations (all six of GLOW, PL612, IE613, LV614). It is very sad that our Ukrainian friends cannot participate with UTR2 anymore. |
| 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''. | All LOFAR(-like) stations observed in RCU mode 3 (band 10_90) with 8-bit recording of 244 subbands (40-283, 8-55 MHz).

| - | 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. | + | These plots show the strong (Io-B?) arc, but unfortunately not the expected (Io-D) counterpart from the southern hemisphere that we had hoped for. The exact nature of these signals needs to be investigated. In any case the signal is clearly strong enough for a VLBI analysis. |

| + | He writes: "(1) It confirmes that the prominent vertex-early arcs are RH polarized (white on the bottom panel) and therefore consistent with Io-B emission (2) at the lowest frequencies, LH emission (black on the bottom panel) is seen continuously after 16:30, including what might be a signature of Io-D emission after 18:00". | ||
| + | |||
| + | This means we have a good chance to see emission from both hemispheres at least at the beginning of our observation. | ||
