Class:
Constellation: Sgr
Data: mag 8.3  size 8.9'
Position: RA 18h 07m  DEC -25° 00'
Description:
This cluster is notably bigger and somewhat dimmer than neighbouring 
NGC6553.
I estimated it's diameter to be 3'40, which is much bigger than other NGC
globulars, that never look bigger than 1.5'. Although I found it without
consulting the map, I couldn't see it all the time, cause it was kind of
popping in and out. From time to time, it looked litle irregular.
In the same FOV, 1° to the N, is NGC6553.
