NASA SkyWatch SkyLog Tab Help
**Click on
a section of the user interface to provide detailed information.**
The SkyLog Tab
is a storage location for orbit sightings that you have discovered during
the course of processing. Whenever you press the Next Sighting,
Weekly Sightings or All Sightings buttons, any sightings that
NASA SkyWatch finds will be stored on this tab. This tab does not provide
detailed data about the sighting, but does give enough information so
that the sighting can be made even without the benefit of the digital
data on the Table Tab or the SkyTrack image.
The SkyLog data is divided into
six columns:
- Satellite - The satellite that can be seen as indicated
on the Input Tab.
- Local Date@Time - The local time the sighting can be made.
- Pass - The number of estimated minutes and seconds that the
satellite can be seen.
- Max Elev - The maximum elevation (in degrees) above the horizon the
satellite will reach during the pass.
- Approach - The approach direction. This is where to start
looking for the sighting. The approach is actually two values, an
elevation and an azimuth. The first parameter indicates the elevation
when the sighting begins and the second parameter indicates the azimuth.
- Departure - Similar to the Approach, the Departure value gives where the satellite will
be at the conclusion of the sighting.
At the bottom of the display are five buttons to manage the accumulated sighting information.
- Sort by Date - SkyWatch will tabulate the sightings in the
order they are found. However, it is more likely that you will want
to view them in the order that they occur. So pressing this button
will sort the list from earliest to latest.
- More Info - To see the detailed digital tabular output and
the SkyTrack image, select one sighting from the SkyWeek table by
clicking on it and then press the More Info button. This will reproduce
the sighting so that the same information is available. The Table
Tab will be displayed for you once the data has been produced. Note
that detail data can only be produced for satellites kept within the
satellite database. This means that any detail data for a satellite that
is manually input will not be available.
- Clear Line - This button will erase the sighting on the row
currently highlight.
- Clear Table - This button will erase all the sightings currently
contained in the table.
- Print... - Up to 30 lines of output can be displayed from
the SkyLog table in a separate browser window so that the browser
print function can be used. If you attempt to print more than 32 lines,
NASA SkyWatch will simply truncate, or shorten, the table by the appropriate
amount so that the maximum number of lines will not be exceeded.
