We present the detection of l=4 and l=5 modes in power spectra of the Sun,constructed from 12 yr full-disk VIRGO-SPM data sets. A method for enhancingthe detectability of these modes in asteroseismic targets is presented andapplied to Kepler data of the two solar analogues 16 Cyg A and B. For thesetargets we see indications of a signal from l=4 modes, while nothing is yetseen for l=5 modes. We further simulate the power spectra of these stars andfrom this we estimate that it should indeed be possible to see such indicationsof l=4 modes at the present length of the data sets. In the simulation processwe briefly look into the apparent misfit between observed and calculated modevisibilities. We predict that firm detections of at least l=4 should bepossible in any case at the end of the Kepler mission. For l=5 we do notpredict any firm detections from Kepler data.
