Magnitude limit is the faintest star recorded at visible wavelengths.3. Speed is the rate at which observations can be carried out. One can see that of the operational facilities, LINEAR covers the most sky per hour (1200 de
gree
2 /hour) but the faintest stars it can observe at this
speed is 19.4 mag. The Spacewatch (1.8 m) telescope can observe stars that are 3 magnitudes fainter but at a speed of only 8.9 degree
2 /hour).
