AGU members who use the telephone to communicate with their colleagues at Goddard Space Flight Center in Greenbelt, Maryland (area code 301), should note that GSFC has switched over to the centrex system, and all telephone numbers have changed. The exchange number (first three digits), which was 982, is now 344. If the fourth digit was 4, it becomes 8; if it was 2, it becomes 7; and if it was 5 or 6, it remains unchanged. The last three digits stay the same. Please note the change on your membership directory.
