(meteorobs) Taurids not so hot

Three mostly-successful meteor observing sessions to report from a very
hectic couple of weeks, might as well present them in chronological order.
This year my meteor project has been to observe every "major" shower (as
listed in the RASC Observer's Handbook, anything with ZHR >= 10) as close to
the listed peak date as possible. This approach has forced me to pay more
attention to previously-ignored showers like the Taurids. As a veteran of
both the Orionids and Leonids I have spotted a fair number of individual
Taurids, it's impossible not to with their very lengthy display every year.
But I had never gone after them specifically at their "peak"before. I had
every intention of going out very close to both Nov. 5 and 12 for the S. and
N. Taurids respectively, both of which had a listed peak of ZHR = 15 in the
Handbook. (The IMO calendar agreed as to the dates of the peaks, although
with a more modest forecast of ZHR = 5)
Alas, fate had other plans, as my father passed away suddenly on
November 4. That night the skies were clear as a bell but instead of
heading to the dark site I packed for a trip to Victoria. A beautiful
conjunction of Venus and the crescent Moon highlighted my early morning
drive to the airport, but I saw not a single meteor. I packed my meteor kit
in hopes of a little backyard observing on the coast, but it clouded up soon
after my arrival and stayed that way for four days until the Sun finally
broke through Friday afternoon during the interment.
By Saturday night I was back home in Edmonton and desperate for a little
starlight to help me regain my perspective, but way too exhausted to even
think of a long drive. So for the first time in my project I chose to simply
observe from my back yard for an hour or so. Transparency was pretty decent,
with a LM of 4.5, about as good as it gets from central Edmonton. While
technically we were closer to the second Taurids peak than the first, I as
sole arbiter of my own project decided to give myself a break and officially
label this a "South Taurids" session. What do you know but all three of the
Taurids I did see were unambiguously from the southern radiant. Also got an
early Leonid and a colourful majestic sporadic for my troubles. Most
importantly, got an hour's worth of night air, alone with my skies and my
thoughts.
