According to the March, 2004 issue of Sky & Telescope (page 103, 106) the asteroid 107 Camilla will occultate the 11.8 magnitude star TYC 5244 0017 on Sept. 5,...
Hi Lawrence, Sounds as if you found the right object. So the only mystery is why it's not showing. When you go to Extras... Toggle User Datasets and find...
Hi Roger, The key here is having the name of the object entered so that Guide "wakes up" and realizes that it's numbered object 407. To do that, the number...
I discovered that for some reason, I don't know why, the Tycho 2 star 5244-0017 is not in the Tycho 2 catalog supplied with Occult. It is in Guide8 so I used...
I placed in the files section of the group, the Goffin Planetary chart which gives general information and locator charts. Steve Preston maintains the IOTA...
Thanks. I downloaded the new Tycho2 and other catalogs listed below and that solved my problem about Occult not finding the Sept 5 event. The new data...
Thanks to Bill and Larry I found that the magnitude setting had gone too low, and another setting (sorry, can't remember) was also wrong. All is fine now. I'm...
Hi Bill and Lawrence, May be this can help you : With my installation, GUIDE shows and labels well the quasars when I use the English, Japanese, Dutch, Czech,...
I would direct your question to Steve Preston (stevepr@...), since he has a better understanding of the processes involved and generates the predictions...
Hi John, Sounds as if you've sorted out most of the Occult and Guide aspects of the situation. If you're going to attempt to get really good occultation...
Hi Jean-Noël, (Groan) Yes, I see this problem, too. It affects languages in which the title for that dataset is not 'Quasar' (for example, 'Quasare' in...
Hi, Bill, Just want to say thinks for your timely support regarding occultation paths. I have ordered the referenced star catalog and also appreciate the tip...
Using the new orbit data from Steve Preston I was able to get Guide8 to match the published predictions regarding the Sept 5, 2004 occultation of TYC 5244 0017...
Hi John, Find_Orb is expecting the Minor Planet Center "standard" format: http://cfa-www.harvard.edu/iau/info/OpticalObs.html This is the standard format...
Hello "toadatrix" (?) Thank you for introduce the "Ast Dys" site. It provides great observation data ! I created convert program using Excel-VBA, and I put it...

I did get your Excel conversion program to work. However, I notice that it seems to exclude all observations before 1990. This leaves 411 observations out of...
Bill, how does Find_Orb select which observations it will use in getting the orbit? I ask because I used the same data you did except I excluded everything...
Hi John, Regarding that five-minute run with the entire dataset: you should probably set up Find_Orb to make use of JPL DE ephemerides. Doing that should...
... I believe we get most of the observations used, from Table Mountain Observatory (Bill Owen) and Flagstaff (Ron Stone). I only say this, since I get a CC:...
WOW! What a speed up in computation time!!! I added the line pointing the enviroment variable to the JPL data in my Guide8 sub- directory and now the orbit...
Does anyone know if the Venus transit will be visible in the SOHO satellite? Is there any way to simiulate what SOHO sees (change location) in Guide so that...
According to the soho site, venus misses the sun, as seen from soho location in space. http://sohowww.nascom.nasa.gov/ Kevin __________________________________...
I was able to get a binary copy of the entire JPL DE406 file (199 MB) all contained in one, single file. Can Guide8 and FIND_ORB use this file over its entire...
Hi Roger, SOHO is "close, but not exactly" at the L1 point. I believe it's referred to as a "halo" orbit, one in which it circles around the L1 point. Guide...
Hi John, Forgot to reply to: "...Does your INTEGRAT function with Guide8 use the same JPL data to speed up the time it takes to update asteroid elements to a ...
Hi Bill and all, There were 2 eclipses which show as total when viewed from Alamosa, Colorado, U.S. They were in 1257 A.D., 13 June, and 1259 A.D., 17 October....
Hi Laren, Looks to me as if you've simply found the following eclipse, an annular one in South America. Click on "Previous", and you'll see the one you're...
