Thanks John.

Hi Roman, those look like classic 'waves', also known as Herringbone structure, similar to ripples on a beach at low tide.  Smiley
Martin, the "classic waves" is IIIb, am I right?

Just a hour ago I had another display here (they occure regularly!  Shocked ), of brightness 3-4 - the best one (yet) this year... There were some structures which I coudn't identify in a short time, now need to do it looking at photos.
I will post a report tomorrow and I hope for your help in idenifying.  Roll Eyes
