MAXI successfully captured First Light images

Last Updated: August 18, 2009

On August 15, 2009, MAXI has successfully captured the First Light images.

The images captured this time were intended to use as data for initial calibrations of the MAXI cameras, such as corrections of exposure time, and corrections of positions and angular. Nevertheless, the images provided the primary X-ray image map, thus it was confirmed that the MAXI cameras functioned properly and achieved the expected performance.

In this way, MAXI will capture so-called "all-sky X-ray moving image" once per orbit (once every 90 min.) from the ISS focusing on the variability of X-ray intensity for more than 1000 X-Ray objects in a observation period from a day to a few months.

In the future, it is expected that MAXI will achieve 10 times more sensitivity compared to that of the existing X-Ray all-sky type observatories.
