What would normally be an easy split was rendered difficult by the fact that I could barely make out the mag 9 companion, due to the clouds.

Magnification: 98x
Rating Scale: 5E <1 to 5 (1 being outstanding
view, to 5, a dismal view) and letter E, M or D (easy, moderate or difficult)>
I noted colors of W and W(?).  Viewed at 98x, this poor urchin gets lost in a bleak field.  OK, OK, it's not that bad-there is a nice little "bowl" of stars that holds it.  But this is sort of like putting a pair of poppy seeds in a silver serving bowl at English Tea Time.

An interesting "model" of this system can be built, using a scale of the Sun being the size of an American baseball (about 3 inches, or 76.2mm, indiameter.  The primary here would be 7.52 inches (19 cm) in diameter, with the B star coming in at 7.57 inches (19.2 cm).  So we can picture two balls about the size of bowling balls, separated by a mere  3.90 miles (6.3 km)!
