We present our observations of six Galactic globular clusters where the following bright Xray sources were observed: NGC 6440, NGC 6441, NGC 6624, Terzan 1, Terzan 2, and Terzan 6. Using the Chandra observatory, we were able to achieve a localization accuracy of 0''.6 for X-ray sources in the globular clusters. The error circle considerably decreased compared to the observations of other observatories, by more than a factor of 10 for some clusters. We detected at least one X-ray source in each of the globular clusters studied and 12 sources in the globular cluster NGC 6440. The source XB1733-30 in Terzan I was not detected by the Chandra observatory; we obtained an upper limit on its luminosity. (C) 2002 MAIK 'Nauka/Interperiodica"
