Does LASCO operate on 7/24 basis ?
The LASCO and EIT instruments aboard SOHO are generally operating on a seven days a week, 24 hours per day basis. However the ground segments (commanding, data reduction, image processing and data archives) are manned on a normal work week (9-5 M-F Eastern time) following the Federal holiday schedule and with snow, hurricane and emergency days for Washington DC. That means that problems with processing (hardware, software, network, power) are not fixed until the next business day. Building maint. also tends to shut the power off once or twice a year on the weekends to work on air conditioning and heating.
