I calculate the Asc at 18degrees 21minutes 04seconds of Sagittarius, with the only major "within orb" aspect to it being :-
Mercury square at 17.45.11 Taurus/9th house (1 degree orb).
The "wider orb" aspects to it (which I'd not use in an interpretation) are :-
Sun trine in Leo/8th (5 degree orb)
Moon sextile in Aquarius/2nd (4 degree orb)
Pluto sextile in Scorpio/11th (6 degree orb)
North Node sextile in Aquarius/2nd (7 degree orb)
(Mercury square Asc results in "what you say often being not what others hear" - so, you have to work hard on learning to communicate your ideas and opinions clearly/in a way that others understand. Bear in mind that Mercury in Taurus/9th is concerned with things of practical value that broaden the mind, and the Sagittarius Asc gives exceptional open mindedness. So, to others, it might appear that your opinions/ideas "change with the wind" unless you explain clearly why "what you believe today is not what you believed yesterday or will believe tomorrow". That's the curse of a mind that simply has to explore things.)
As Flea says though, Astro.com produce charts correctly/in accordance with the data input.
