The ALON/ALAT is 45/24. Magnetorquing has ceased, and the satellite will begin drifting toward ALON of approximately 315 degrees. This will take approximately four weeks. This is done twice a year to keep the satellite healthy due to poor sun angles. Although the satellite's passbands are off, its beacon remains on and FEC telemetry is active whenever possible. According to AO-40 ground controller Stacy Mills, W4SM, the passbands should be back on in time for the Christmas holiday. The AO-40 team would like telemetry files.
