SB 12.2.27-28

saptarsinam tu yau purvau
 drsyete uditau divi
tayos tu madhye naksatram
 drsyate yat samam nisi
 
tenaiva rsayo yuktas
 tisthanty abda-satam nrnam
te tvadiye dvijah kala
 adhuna casrita maghah
 
Translation: 
 
Of the seven stars forming the constellation of the seven sages, Pulaha and Kratu are the first to rise in the night sky. If a line running north and south were drawn through their midpoint, whichever of the lunar mansions this line passes through is said to be the ruling asterism of the constellation for that time. The Seven Sages will remain connected with that particular lunar mansion for one hundred human years. Currently, during your lifetime, they are situated in the naksatra called Magha.
