So far this year, we have received more than 11,000 measurements from across the world! Ten countries (excluding the US) have achieved the “Over 100” Club status, meaning that more than 100 measurements have been submitted from these countries. Our members (in order) are:

Croatia (1258), Poland (1171), Chile (1094), South Korea (528), Macedonia (FYROM) (274), Japan (207), India (145), Canada (133), Romania (109), and Spain (107).

In the United States, five states have achieved the “Over 100” Club status. They are (in order):

Arizona (819), South Carolina (577), Texas (552), Oklahoma (225), and New York (124).

Congratulations to all our members! Across the board, limiting magnitude 3 is the most common submission we receive. Next year can we make it 4?

Globe at Night Spotlight

Our Globe at Night spotlight this month features two 7th grade teachers and their science classes at Mansfield Middle School in Tucson, Arizona. Each month, the teachers used Globe at Night as a homework assignment. From January through April this year, they have collected more than 350 data points! (See their data points in the map.) That accounts for almost half of all the points taken in Tucson! Way to go, Mansfield!
