- Keplerian bulletins are transmitted twice weekly from W1AW.
- The next scheduled transmission of these data will be Tuesday,
- October 11, 1994, at 2230z on Baudot and AMTOR.

- MA stands for mean anomaly. It is a number between 0 and 256. It is used to
- locate the satellite in it's orbit. For example, MA 0 means the satellite is
- at perigee (point where satellite height is minimum). At MA 128, the
- satellite is at apogee (point in orbit where satellite height is maximum).
- With MA between 0 and 128, the satellite is headed toward apogee. Likewise,
- if MA is between 128 and 256, the satellite is headed toward perigee. Note
- that MA 0 and 256 refer to the same point, perigee.
-
- The MA is frequently used to indicate when transponders will be turned on
- and off during any orbit.
