2023 Occultations by Main Belt Asteroids - Updated September 9

IOTA campaign occultation of 9.1-mag. star by (704) Interamnia, night of Sept. 12/13


These occultations are described and illustrated (in maps and tables) 
in this .pdf document. It includes several hot links to external Web 
pages, but links to internal files, the .xml input files 
used by the Occult program, are given below. 

2023 SEPTEMBER 13 OCCULTATION BY INTERAMNIA, S. CALIF. TO NEW YORK

This occultation, which only barely didn't make it to appear on our map
of the brightest occultations of 2023 in N. America, is now our IOTA 
campaign event of 2023, as described on the IOTA Campaigns Page.
This message sent to IOTA observers via the IOTAoccultations groups.io
list server on September 8 gives more links and information about the 
event. We plan to start the Sept. 11th evening Zoom session about pre-
pointing for the occultation at 2:30 or 3:00 UT of Sept. 12, starting 
with a fairly detailed PowerPoint presentation and followed by a live 
demonstation, weather-permitting. Finally, another Zoom session will 
start several minutes before the shadow first reaches N. America's west 
coast at 10:15 UT of Sept. 13 and will continue until after the shadow
reaches New York 3 minutes later, with wrap-up lasting for several min.
later, until those attending are ready to call it quits for what is 
left of the night. If you are interested in joining either of these
Zoom sessions, send a brief e-mail to joan_dunham [at] yahoo [dot] com .

OCCULT INPUT FILES FOR 2023:

When you open these files with your Web browser, you should get a display 
that looks like this. The larger files may take a couple of 
minutes to show this appearance, showing a messed-up display before then. 
Once the proper view appears, right-click anywhere on the display, then 
"Save as" to a directory on your computer; the best directory is the 
\Asteroid\ subdirectory in your Occult\ directory.

25 North American main belt events to mag. 9.0, in the Handbook and the .pdf file.
152 North American main belt events to mag. 11.0
453 North American main belt events from Steve Preston
Worldwide major planet and satellites events from Dave Herald
Worldwide main belt events from Steve Preston
 - for them, prediction maps and data are available at https://www.asteroidoccultation.com/.
But note that Preston updates and adds many events every two weeks, so they are comprehensive
only for the next two months. Occult Watcher, described in the .pdf document, is 
the best way to find out about updated upcoming events near your location.
