This theoretic radiant should be quite recent. I have found
that this object was near Jupiter in 1986 and in that case
the orbital plane changed. Until that time, the orbit had
incl= 7.8 and node= 51.1 (May 12) and it was very unlikely
the theoretic radiant in ARI (alpha 38.8, delta +27.8) showed
meteors, as the distance orbit/Earth was about 0.26 AU. After
1986 this radiant moved in TRI (alpha 35.4/36.5, delta +34.0/
/+34.5 for April 22 node=31.7) with a shorter distance orbit/
/Earth (from 0.05 to the current 0.02 AU), compatible with a
theoretic display of meteors. But anyway the radiant, always
very near Sun, is undetectable both morning and evening.
Best,
Enrico
