To paraphrase the kiddies of today, "OMG Ponies!!!!"
I got to travel to the Kennedy Space Centre to watch a Delta II launch carrying the Kepler mission. It was a magnificent sight. What shocked me was how bright the it was. Luckily it was a very clear night, so one could see the boosters separate and fall back down to the Earth. You can see them glowing in the picture above.
Way go to Kepler!

New Building for Burton Meats
Very cool. My parents and brother have moved into a new building. Impressive new place. I especially like the addition of the retail store!

Kepler Bandpass
The transmission functions for the Johnson B,V,R,I filters are shown from left to right in blue, green, red and magenta respectively and have been scaled to peak at 100% transmission. The Kepler bandpass is shown in black which peaks at approximately 70% throughput. The CoRoT whitelight bandpass is shown by the dot-dashed line. The MOST bandpass is shown by the dashed line. The spectrum for an A2V star is shown in cyan, which peaks in the UV and the spectrum for a M2V star is shown in orange which peaks in the infrared. The two spectra have been scaled to have equal flux in the Johnson V filter.
If two stars of two different spectral types have equal brightness in the V filter, then one would like to know what is the difference in flux over the Kepler bandpass for the two stars. One starts by defining that a G2V star will have equal brightness in the V filter and Kepler bandpass. This definition provides a natural way to scale the artificial spectra and to compute the flux difference in the V filter and Kepler bandpass as a function of spectral type. The Figure demonstrates how a hot A2V and cool M2V star with equal brightness in the V filter can have quite different brightnesses through the Kepler bandpass with extends to the near infrared part of the spectrum.

Don't Touch the Ash.
umm.. warning to the people of Prince George not to touch the ash, so CBC shows a picture of a resident holding up ash and posing for a nice photo. I hope his hand is okay.

Hockey, Hockey, Hockey
With the Leafs not making the playoffs, I've had an open mind concerning who to cheer for in the playoffs (except for Ottawa, very happy to watch Ottawa loose!). This has changed in round 2. My picks are:
San Jose, Montreal, Pittsburgh and Colorado.
So far, I'm not doing so well. I can't stand Philly and their rude fans. Who boos O'Canada and chants U.S.A. over and over? No respect. Considering a large portion of the team are Canadian Natives - including goaltender Biron - the fans should give their head a shake.
Picked San Jose, as that's where I live now, and the team has good talent. They just need to learn how to perform in the playoffs. Don't really care for Detroit or Dallas.
If trends continue. I guess I'll be cheering for Sid the Kid.

Planetary Models.
I've been working on a planetary atmosphere dynamics model for the last while and I've finally made some real progress. Here's a video showing the local vorticity.
Vorticity is a measure of the spin potential.

Finding planets by timing transits.
There are about a dozen exosolar planets that transit their host star (a transit is when the planet moves in front of the star blocking out light). Measuring the when transits occur can be a powerful tool to determine if other planets are present in that system.
The Figure above shows a simulation of transit timings if additional planets are present. The primary planet has a mass of 0.69 times the Jupiter and an orbital period of approximately 3.52 days. The colours indicate the mass of secondary planet, ranging from 1 to 100 times the mass of the Earth. The scale on the bottom shows the period of the secondary planet ranging from 1 to 17 days. The scale on the left indicates the change in the occurrence of the transit event. It is a log scale (0 -> 1 sec, 1 -> 10 sec, 2-> 100 sec and so on..).
Long term monitoring of transiting systems gives the opportunity to possibly discover other Earth-sized planets outside out Solar System.
