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.
