The time draws near to the chase. Sirius must be driven away from the Sun so that we can rid ourselves of this long hot sweltering summer (Northern Hemisphere). In 2 days, the Dog Days of Summer Challenge will begin. The 48 hour Challenge is being offered on PrimeGrid's 321 Prime Search (Sieve) application. Please come join us as we quicken the return of cooler days.
