The following is a text file that I downloaded from Amsat-DL.
It outlines the plan for AO40 for the next few months.

AO-40 Update 2. March 2003
We are continuing to move ALON forward to keep the solar angle
within range. The current ALON/ALAT = 15/0 (nominal), and we are
slowly moving to ALON =20, but this will take about 6 more orbits.
To compensate for the change in squint the K-window has been moved.
Further passband shifts will come when we reach ALON=20.
Here is a provisional schedule of things to come:
We will continue slowly moving ALON forward toward 45 degrees during
the month of March. In early April we will begin raising ALAT toward
20 degs. By mid-April we should be at ~ ALON/ALAT = 45/20. Passband
activities will be turned off at that time. We will drift for
approximately one month, arriving at ALON/ALAT = 315/20 in mid-May.
We will then lower ALAT to 0, restart passband activities (shifted
to the early part of the orbit), and begin moving back toward ALON =
0, chasing the sun at the rate of about 1 deg/day. We should return
to ALON/ALAT = 0/0 about June 20th. We can stay at ALON/ALAT = 0/0
until early October, when the cycle starts over. Thus, expect the
passbands to be off from about mid-April to mid-May, but active at
varying phases of the orbit, the rest of the time. We should be in
good position for field day, just getting back to 0/0.
