摘要: PREVIOUS observations at Sheffield of radio echoes from Quadrantid meteors have shown a marked increase in the numbers with enhanced duration (>2 s) some tens minutes after sunrise on echoing layer (unpublished work T. R. Kaiser, F. Nicholson and L. M. G. Poole). During 1972 Quadrantids this occurred 0830 UT, about 60 min time when solar zenith angle was 91°.
