(meteorobs) Re: Clusters & 3 Letter Codes
Kim,
If I saw a cluster of radiants occurring in one area of the sky I would
label them as sporadic but make a note of this occurrence in my
observing log. I would try to observe the very next night to verify any
continued activity. The following year I would try to do the same. If
this activity repeats itself for several years then you are on to
something.
If we had each observer making up their own 3 letter codes it would
tend to create chaos to those who try to analyze such data.
Out of curiosity Kim, were you facing toward Sagittarius while
observing? If not I would bet that this activity was actually radiating
from the constellation of Scorpius which is the center of the current
anthelion activity which includes the Sagittarids (SAG), Alpha Scorpids
(ASC), and both the Northern (NOP) and Southern Ophiuchids (SOP).
