“…Such alerts are not possible now, but several near flybys were reported. A few years ago a graduate student in Tucson, Timothy Spahr, discovered a 300 meter diameter asteroid 1996 JAl, passing within 450,000 kilometers of Earth (Spahr 1996). It reached 11 mag at the closest approach:…”

Abstract. Variability in the sky has been known for centuries, even millennia, but our knowledge of it is very incomplete even at the bright end. Current technology makes it possible to built small, robotic optical instruments, to record images and to process data in real time, and to archive them on-line, all at a low cost. In addition to obtaining complete catalogs of all kinds of variable objects, spectacular discoveries can be made, like the optical flash associated with GRB 990123 and a planetary transit in front of HD 209458. While prototypes of parts of such robotic instruments have been in operation for several years, it is not possible to purchase a complete system at this time. I expect (hope) that complete systems will become available 'off the shelf in the near future, as monitoring bright sky for variability has a great scientific, educational and public outreach potential.
