Got a great view of all 7 strung out pretty evenly in a line. At culmination, they spanned about 15 deg (19:18? UT). All were visible to the naked eye at around mag 5, but the 3rd last one brightened to 4 in Ophiuchus. Others seemed to change brightness whilst I looked in binoculars. As they descended in Hercules, I could fit all 7 in the 10x50B field. Brilliant! Cheers, Rob
