Asteroidal Occultation Report Form

Back to Results page

Many thanks for your reports and observations !

All data entered on this form are transferred by e-mail (if your browser/mailer configuration supports this) and are treated as non-secret.
You don't have to enter all items, however to fill more items is better.
To jump between text fields use the TAB key.

This form uses client-side mailing and (unfortunately) doesn't work correctly for all combinations of mail programs and web browsers. Basicly it should work if you have beside the web browser also a correctly configured local mail program (Eudora, Outlook, Outlook Express, ...). It's possible that after clicking the 'Submit' button you will have to confirm one or more security questions from your mail program before the form is really sent out.

I have checked that this form worked correctly for me with MSIE (version 4.0 or newer) together with Outlook, Outlook Express or Eudora. It also worked with Netscape 4.79 and 7.1 or Mozilla 1.1 and 1.4, but definitely not with Netscape 7.02 or Opera 7.11

If anyone filled this form and didn't received any notification please contact me or please report the events once more using plain text forms available - E.A.O.N. or  IOTA variant. Sorry for any inconvenience.
