Beijing Schmidt CCD Asteroid Program

The BAO Schmidt CCD Asteroid Program or Beijing Schmidt CCD Asteroid Program or SCAP was a project organized in May 1995 by the Beijing Astronomical Observatory and funded by the Chinese Academy of Science. Its purpose was to discover near-Earth asteroids (NEAs) and comets.

Device

The instrument that SCAP used to detect near-Earth objects was a 60/90 cm Schmidt telescope. Equipped with a 2048×2048 CCD camera, this telescope was installed at the BAO Xinglong station in Hebei province, China.

Discoveries

From 1995 to 1999, SCAP detected one new comet and 2460 new asteroids and observed 43860 other asteroids, making it the fifth largest asteroid observation project at that time. Five of the asteroids it discovered were NEAs, two of which were considered potentially hazardous asteroids (PHAs). In 2002, an NEA was discovered near Earth's moon.

For some reason, about half of its discoveries are credited by the Minor Planet Center (MPC) to "BAO Schmidt" and the other half to "Beijing Schmidt". It is extremely likely that these are one and the same.

Recent status

In a conversation with Space.com contributor Michael Paine, SCAP head Jin Zhu said that the program's allotted time to use the Schmidt telescope was significantly reduced to make room for the observatory's other projects.
