Yes, as in 24 hours. My mission is to create a 24-hour observatory by linking 1-meter class telescopes at Lick Observatory (California) and Skinakas Observatory (Crete). The sites are separated by 10 time zones. Thus, when the sun rises at Lick, the sun sets in Crete. The advantages of 24 are that both facilities provide sensitive NIR cameras, optical spectrographs, and adaptive optics. Both sites can be controlled remotely, and until they are fully robotic, 24 offers observational astronomers a test of willpower and endurance.
