- Comet 1995 O1 (Hale-Bopp) in 1997
-
- The file "C1995o1.lab" contains the positions of the (hopefully)
- bright comet, "Comet 1995 O1 (Hale-Bopp)", at five day intervals,
- throughout 1997. By all accounts, it should be a spectacular object
- around March/April 1997, easily visible from the northern hemisphere.
- If you missed last year's comet then don't miss this one - but don't
- expect to see the rumoured alien spacecraft accompanying it ;-)
-
- The file is formatted as a Solun labels file. Whilst it is designed
- to be viewed graphically on a Solun starchart display it can also be
- read directly with the standard Data application.
-
- Each entry in the file describes the position of the file at a
- particular date. When plotted on a starchart, the labels appear as a
- string of dates that represent the apparent path of the comet.
-
- To use with Solun (v3.0d or later): Copy the file to a "\APP\SOLUN\"
- directory. From within Solun, use the "Label files..." menu option
- (Psion-F) to choose the file, remembering also to activate the
- labels with the "Active" item . Read the Solun manual, Solun.wrd, for
- more details of label files. This file is best viewed with the
- registered, Series 3a version of Solun.
-
- To use with Data: Rename the file to "C1995o1.dbf" and copy it to a
- "\DAT\" directory. The file should appear under the Data application
- where it can be opened as usual. Each record contains three fields:
- "r" - right ascension; "d" - declination; "l" - date on which comet
- will appear in the approximate position.
-
- Please read the Psion manuals for details of copying files to your
- machine.

-
- The data contained in the file, "C1996o1.lab", was derived from data
- dated 8th November 1996, and published at the following WWW address:
- "http://www.eso.org/comet-hale-boop/hale-bopp-eph-nov96jan98.txt". I
- make no guarantees of it's accuracy. I could have very easily made a
- typo.
