** Past trips
------------------------------------------------------------
* A group of optimists again gathered for evening skiing at Cypress. After a bit of hiking and skinning, the group skied down with the sun setting over the Howe Sound. Picture courtesy of Nicole Ong.
* Son of Rock happened this past weekend. Amongst many things, people climbed, swam in the river, sat around a bonfire and were treated by the spectacle of a proton arc and the aurora! Picture taken by Lena Förstel.
* Throwback to Unusual climbs in Garibaldi in 1958 (http://www.ubc-voc.com/2016/05/10/unusual-climbs-in-garibaldi) by Artem Babaian. A new throwback will be posted every fortnight on Tuesday!

Dear Ms. Manners,
What distinguishes a contrail from a proton arc?
Sincerely,
Sceptical Climber
Dear Sceptical Climber,
Let's put on our physics glasses. A contrail is a cloud formed from the exhaust of an airplane when water vapor condenses and freezes around particles in the exhaust. Contrails can be seen at night, although they are often irregular and quickly disperse due to winds in the atmosphere. A proton arc is formed when protons emitted by a solar storm interact with the atmosphere. As you and the many climbers at Son of Rock and in Squamish saw this past weekend, the proton arc formed a smooth, straight arc across the sky in the East-West direction which lasts longer than a contrail and is also brighter. It is generally accompanied by the typical aurora, as was the case this weekend. If that isn't enough to convince you that you saw a proton arc, then you probably never will be convinced.
Sincerely,
Ms. Manners
