The star is magnitude 11.05, and 70 Panopaea is magnitude 12.90 according to
Cartes Du Ciel. Set your setting circles!

Hi all,

I just uploaded the Asteroid Orbital Elements Database (ASTORB) from the
Lowell Website and put it into Cartes Du Ciel planetarium software. Seeing
that the Central Bureau for Astronomical Telegrams hasn't uploaded 2008 data
for a lot of planetarium software, making it very difficult to put the
ephemerids for 70 Panopaea into Cartes Du Ciel, I decided to put screenshots
of the star charts onto this page:

http://picasaweb.google.com/mhilario2/

There are 5 star charts: 1 deg, 2 deg, 5 deg, 30 deg, and 60 deg. Please
navigate to the 70 Panopaea folder, click on the star charts, then click
"DOWNLOAD PHOTO" on the right sidebar. Star magnitudes on the charts are mag
5.5 to mag. 12. North is upwards in each chart. The most helpful image is
probably the 2-degree chart. It has a large circle for 2 degrees and an
inner circle for 1 degree, similar to the view you will have with an 8" SCT
and 40mm eyepiece. You can also use the 60 degree and 30 degree charts to
starhop.

------CARTES DU CIEL USERS ONLY---------

The online resources - asteroid elements in Cartes Du Ciel are not currently
working...so below I put my method of getting the Lowell Observatory's
Database into Cartes Du Ciel. From here, you can view the positions of about
400000 asteroids. It is pretty cumbersome and you have to be somewhat
computer savvy, so it might take about an hour or two.

1.) Download and install Cartes Du Ciel star charts if you have Windows:
http://www.stargazing.net/astropc/download.html
a. Complete package
b. 2.76c update
c. Tycho2-Part1
d. Tycho2-Part2

2.) Right click on this link below and "save link as" to the folder
C:/program files/ciel/cat/planet

ftp://ftp.lowell.edu/pub/elgb/astorb.dat

It's a 106MB file, so you must bear with it.

3.) Open up Cartes Du Ciel, put in your observing location coordinates then
in the file menu bar...
Preferences>Catalog and Objects Parameters>Asteroids

4.) Then in the "source" box on the right side, click the radio button
"Astorb"...then click "Refresh"

5.) In the box, select "70 Panopaea" then click "OK"

6.) On the right side toolbar, click on the "clock icon" and type in the
time of occulatation, which is 22:07 on 11 Jan 2008.

7.) In the file menu go to:
Search>Find>Solar System>Asteroids>70 Panopaea then click "OK"

You now have a current, working list of 395692 asteroid ephemerids!!!
Starcharts galore, astrometry, and photometry galore. Hopefully Cartes Du
Ciel will fix their program soon, so its easier and faster to get the data
online through their online resources.

------END OF CARTES DU CIEL USERS ONLY---------

As for me...I'll be at Redstone using shortwave radio (20Mhz) for the
occultation timing. Also in use will be a mallincam at 2x integration, 10"
dob with Cyanogen Maxim DL/Virtual Dub for image capture, video frame
timing, & photometry, and 3" refractor for visual confirmation. I don't have
a KIWI-on screen display time stamp for the camera, so I'm in the process of
looking for a software timestamp or at least any software that gives time in
milliseconds.

If you find any websites, suggestions, or anything concerning this asteroid
occultation, please post them on this thread. Thanks.
