Dear Miss Northcott

      I enclose report of variable stars for month of October, you will notice that I have received charts from W. Campbell, & I figure I have enough to keep me busy for quite a while, yet it seems that once one gets the field in ones head, its easy picking.

Dear Miss Northcott

I have nothing of importance to report this month.

have a rotten cold for 3 weeks from being up at Crystal Lake.

Some gentlemen from Barrie came on evening at 10:30, and they were amateur astronomers. I was at work, until 2:30AM so missed them.

The Perseid meteor shower is set to light up the sky tonight!

On 12 Aug, 2013 By Anonymous (not verified)

Each year between late July and early August, the Earth passes through comet Swift-Tuttle’s debris. The debris (mostly bits of dust) burn up in the atmosphere and the result can be a spectacular meteor shower. One of the best opportunities for viewing will be across the northern hemisphere between 11 p.m. and 6 a.m. tonight (August 12). Look toward the northeast (Perseus), but expect to see the meteors in any part of the sky.

Asteroid (2710) Veverka

On 28 Jul, 2013 By ebriggs733@gmail.com

Named in honour of Joseph Veverka, planetary astronomer at Cornell University. One of the first to study the polarimetric and photometric properties of asteroids, Veverka has made substantial contributions to our knowledge of other small objects in the solar system, notably in his detailed work on Phobos and Deimos. He has also studied the morphology and motions of wind streaks on the Martian surface and has been a strong advocate of space missions to comets.
