I like to watch variable stars with an 8 inch Newtonian reflector
I made in my basement. One of my favorite stars is the dwarf nova SS
Cygni. I made a light curve of
SS Cygni during the summer of 1993 based on my visual observations (the
diamonds) and visual observations I received by e-mail from Japan (the
plus signs). The curve shows two normal explosions separated by 3
Another star that caught my eye was the eclipsing binary RZ Cas. On
one cold (-30 C) night I photographed the star with a 35mm SLR camera
with a 50mm lens. From the photographs I was able to estimate the
star's magnitude as the big dim red star passed in front of the bright
small blue star. The light curve
I plotted shows what happened.

AAVSO report software
For those who make less that 50 variable star observations per month and
who use the AAVSO report program, I have posted software that converts
the output of the AAVSO program into a LaTeX file.

Western Canada Fireball (see the list of my papers or download a preprint). The

on the North American Fireball Camera Network.

E-Mail message from Andre Knoefel of FIDAC:
Today's newspapers and TV news reported that a fireball appeared over
Saitama and Ibaraki prefectures about 16:20 (UTC+9h) on January 7.
The fireball travelled in an approximately easterly direction.
An explosive sound was reported.
The event was captured on photo/video recording by the residents.
A probable fragment (5cm, 60g) of the meteorite also was found.

Comet 17P/Holmes on October 26, 2007, 04:15 U.T. at 273x, right. Its position (2nd magnitude) in Perseus is shown, left. No apparent tail, diameter roughly twice the apparent diameter of Jupiter.
Comet 17P/Holmes on November 3, 2007, 01:35 U.T. at 91x, right. Its position (3nd magnitude) in Perseus is shown, left. Surface brightness much lower than on October 26. Appearance now fuzzy in 50mm finder; it was starlike on October 26. Not a perfect sphere anymore - fills 80% of the FOV at 91x.

Canada Customs Clearance number for telescopes is 9005801000. The the
Revenue Canada Customs Clearance number for Telescopes, parts and
accessories is 9013903010. Telescopes and related accessories are
subject to the GST. As for duty, any telescope with a primary
objective, whether it be the mirror or lens which has a diameter under
18" or 456mm ( 45.6cm ) is free of any duty. If the objective is larger
than 18" they refer to it as a research grade and has a duty somewhere
around 3.5%. Eyepieces, for example, are exempt from duties when we
import them, but sometimes things go wrong, and they charge a duties,
which are difficult to have refunded. If you ship in a telescope by

carrier or courier, they will charge you a "brokerage fee", or, IMHO, a
- Deep Space (software)
Although there, as yet, no physical solution for the equations of
general relativity to allow faster than speed of light travel, there is
a mathematical solution. This solution is published in the May 1994
issue of Classical
and Quantum Gravity by M. Alcubierre. (Your institution needs to
have a paid subscription to that journal before you can download the
paper but Alcubierre has made a preprint
available.) I plotted his warp fields using Mathematica. The view of
the field as presented in Alcubierre's paper is shown above and
contoured slices through the field are shown below:
The contours represent space around the starship that is compressed
(left) or dilated (right) with respect to time.

Rotation of Earth-Crossing Asteriod 2006 VV2
The lightcurve below was produced in a 3-hour run between Mar. 29 06:00 UT and Mar. 29 09:00 using SBIG STL-1301E and ST-9XE cameras on 12" f/6.3 telescopes and a V-band filter from the University of Saskatchewan. In this period, approximately 260 images were taken to produce this curve.
The curve is chaotic, showing the many faces of this asteroid, and indicating that the asteroid rotates in multiple axies, and the entire repeating cycle is longer than 3 hours. What is surprising is that sharpness of the minimae which may indicate an angular or facetted shape to the asteroid.
The curve is from raw data, and some work will be required to remove spurious affects. Points above or below, and away from, the general line are due to appulses with field stars or, in some cases, cosmic ray hits on the image or comparision star. The light curve will be cleaned up at a later date.
The magnitude range is relative to an 8.3 magnitude field star defined as 8.300V for the run. Since the camera had to be moved 6 times to follow the fast motion of this asteroid, all photometry had to be done by transferring standard stars from frame to frame. However, the result of this process does not, in this case, introduce an error in excess of 0.05 magnitudes across the run.
