(meteorobs) God's wonders return to Earth

[Eric Bynum]

Dear Mr. Lyytinen:
       The people of Finland must not ever forget that they fought to 
preserve their territory (on numerous occasions) in the face of aggressive, 
expansionist aims on the part of the former (thank the Father) U.S.S.R.    
You have great courage; I respect that.    May the Lord Jehovah bless you in 
all of your future endeavours.   Yes, I pray that this comet will approach 
this parasitically-infested planet in the manner that you described so 
passionately and so completely.

>EL> The 1-rev. Lyrids trail passes quite close to the Earth in 2006, but a

>EL> " ..when I analysed our 2005 Lyrid video observations I found enhanced
>EL> activity
>EL> betwen about 00:30 and 2_30 UT on April 22.

>EL> ... Our result fits quite well, even though its no proof since
>EL> interference from the moon and twilight could explain the result as

>EL> The peak time was predicted at 1:30.

>EL> In this year the time of encounter is predicted at sol.long 32.031 .
>EL> This is April, 22 at 9:25 UT. This can be possibly observed in 
>Americas.

>EL> Assuming the trail density-decline (outside of trail-center) to be like
>EL> in young Leonids trails, a comparison with last year would yiel now
>EL> about 60% the (eccess) rates of last year.
>EL> The meteors from this trail encounter are expected to be mainly dim. So
>EL> under very good conditions and/or sensitive video cameras this increase
>EL> may be detecred, maybe not? (The Moon is a little past last quarter, so
>EL> makes harm especially for faint meteor observing.)

>EL> Encounters other than the 1-rev. trail can not be predicted, because 
>the
>EL> parent comet motion would need to be known back to the return of 
>ejection,
>EL> Some level outbursts that were not from the 1-rev. have been mainly
>EL> observed when the 1-rev. trail is quite nearby like now. This kind of
>EL> outbursts were observed (among others) in 1945 and 1946. This was 60
>EL> years ago which means that there are 5 Jupiter orbital periods and 2
>EL> Saturn orbital periods in between.
>EL> On the other hand if those encounters were for example from 2-rev.
>EL> trails, then in the first return of these meteoroids, Jupiter would 
>have
>EL> been at about the opposite side of the Sun, which would make the
>EL> situation quite differet and not especially promising.
>EL> However, it is worth to try to observe now also possible ouburtsts that
>EL> are not from the 1-rev. trail. I can not give any timing prediction for
>EL> this, other than the annual maximum.
