[vsnet-chat 3495] Re: delta Scorpii : Lunar Occultations table

[no name <crawl@zoom.co.uk>]

Actually, if the expanding disc/shell/both/whatever manages to find
enough old circumstellar material or interstellar material to lead to
radio emissions, there's an occultation a month from Sept 2003 to Feb
2005 for anybody who happens to have a VLBI radio setup to hand...

'lo Stan

there appears to have been an event in late Jan 1968 when delta Sco was
within 15' of lunar disc centre, which sounds like a grazing occultation
to me, but January doesn't smell right sun-position-wise to me [mid-time
was 22.8 UT for example!].

Maybe somebody else knows better.

Other ones from roughly that part of the sky that seem to fit your
timezone & could have been grazers are Deneb Algeidi [tail star in
Capricornus] around 8h30m UT on 5/9/68 [UK sept _not_ US may].  There
was one of Antares on 10/9/67 around noon UT which was 13' offcentre.

Apparently there _was_ a bunch of lunar occultations of delta Sco in
'67/'68 though... ...lets see, 2003,4 minus 1967,8 =  36 and a bit, or 2
x 18 and a bit... ...that'd've pleased that Meton bloke ;)

Cheers

John
