		| Abstract: | 
		The SIMBAD web server generates log records for every query. In the last years, the number of queries increased from 30,000 to 200,000 queries per day. This gives a good basis to make some data mining  among this information.  Using the available data, and a database of geolocalisation by IP address, we can find many unusual results: from session duration to preferred working hours in countries and the most and less active countries in astronomy. |
