✦ Synopsis

We present the results from the second long-term (sixday) observation of the Seyfert 1 galaxy MCG-6-30-15 with ASCA. Owing to extremely good photon statistics, we detected a H-like sulphur (S xvi) edge in addition to the previously reported O vii and O viii edges. The broad iron emission line with a red tail is confirmed. We investigated the variability of the iron line feature with a timescale of 2 × 10 4 s throughout the observation.
