Abstract: | Whereas nearly all previous observations of Cyg X-1 with good time resolution have been made when the source was in its low emission state, Ariel-6 has been fortunate to observe it during 1980 June–July mainly in its high state, i.e. with enhanced low energy emission. The fluctuations were studied on all time-scales down to 2 ms and appeared similar to those previously reported for the low state. The cross-correlation of rapid fluctuations between two bands above and below 3.5 keV however showed a small but significant asymmetry with the high energy emission delayed. |
