Re: [guide-user] 1999 KW4 elements/Tycho-2 CD-ROMs

Hello Claude,
 
Do you have the "use MPCORB" options on in the "extras" menu ? when it switch it off, I get the same message  "Not an asteroid". Entering "J99KO4W" (or J99K04W") gives this mesages, even with mpcorb on. So I use "1999 KW4", then it works OK.
 
Clear skies,
Jan

Hi all,

I was unable to see this asteroid in Guide7. I downloaded the latest
version of Guide and followed the herein given instruction. When I do
Goto Asteroid and type in "1999 KW4", Guide tells me "Not an asteroid".
Entering "J99K04W" makes Guide crash (at address 020202020)

How should I proceed ?

Thanks,
Claude

Hi folks,

   Just a couple of short notes of possible interest...

   If you save this message as a file,  then start up Guide and
use "Extras... Add MPC comets/asteroids" to load that file,  then
Guide will use the following line to update the elements for the
near-Earth asteroid 1999 KW4.

J99K04W 16.6  0.15 K0141  30.585 192.595 244.945  38.895 0.68841
0.64230
3 S

   The above line comes from MPEC 2001-K23,  a "Daily Orbit Update"
(DOU),  available at

http://cfa-www.harvard.edu/mpec/K01/K01K23.html

   You need not modify this message;  Guide is bright enough to dig
through it,  spot the above line,  recognize that it's an orbit in
one of the formats that it knows,  and ignore all this extra text.

   Also:  Claes Schibler mentioned to me via private e-mail that
the Tycho-2 CD-ROM can be obtained from Erik Hoeg in Denmark:
