Looks like I’ve won the prize !!!

ref Minor Planet Centre

The standard designation consists of the following parts, all of which are related to the date of discovery of the object:

2012 a 4-digit number indicating the year;
D a letter to show the half-month; ie D = second half of February, see website
A other letter to show the order within the half-month; A ie 1st BUT
14 optional number to indicate the number of times the second letter has been repeated in that half-month period ie 14.
which I think means that there were 325 ( 13 x 25 {ā€˜Iā€™ is not used so only 25 letters used} ) Near Earth Objects identified in the second half of February 2012.
