Crystal clear skies and bad seeing returned, unfortunately. Anyway, I would like to call your attention to the modifications observed in the dark NNTB bar. In 21 Sept it was still a dark line, in 26 Sept it was observed as two closeby dark components (f component less elongated) and on Oct 3 it was very faint if visible at all (unfortunately bad seeing on this day). Visualy distinct earlier, I could not see it in Oct 03. Any confirmations? Just an effect of bad seeing? Regards and good observations to all Antonio
