I also noticed visual activity from this source some hours earlier. From 00:40 to 01:45 on October 27, i observed 4 meteors from this source. Unfortunately the sky was not clear on the evening on October 27, so i can not confirm the radio observed activity around 23:00 UT. My observations can be found in the visual meteor database of IMO, observing session number 75471.
