Following report was mailed to NMS-Mailing list and I am sending to IMO-News
under permission of the author. Japanese visual observer missed the maximum
but caught rather active display. Especially, K.Suzuki, Radio reflection
observer, recorded more echoes at 11d 10h(JST=11d 01h UT) than former years.
