    Since 2005 the majority of my observing time has been spent studying variable stars. Unlike many variable star observers I don't find monitoring cataclysmic variables particularly interesting and this is despite the many excellent web sites that exist. On the other hand the web site of the American Association of Variable Star Observers (AAVSO) has proved to be a fruitful source of fascinating projects.
    Although I made a few variable star discoveries in 2005 - as reported in IBVS and a slightly larger number in the first half of 2006 - as reported in OEJV - I tended to drift between the different sub-sections of the hobby in a rather unstructured manner.

    approach, with varioussignificant modifications and
    I have consistently spent almost as much time on astronomical data mining as on practical observing and I have had varying degrees of success in the work I have done. For example I have managed to find 1350 previously unreported variable stars in the archives of the Northern Sky Variability Survey. and these have all gone through a peer review process and are now listed in the Variable Star Index maintained by the AAVSO. On the other hand my attempts to get my new double star discoveries listed have been unsuccessful.
    It is much the same story with articles I have written. I have been lucky enough to have material accepted by the Journal of Double Star Observations, the Open European Journal on Variable Stars , the Minor Planet Electronic Circulars and of course the Webb Society and the British Astronomical Association. However some of the material I write receives little feedback - which rather implies that few people read it. Oh dear!

    The title of my project was How the Size of an Asteroid Affects the Speed of Its Rotation, and I hypothesized that the smaller the diameter of an asteroid the shorter its rotation period would be. I choose four m-type asteroids (322 Phaeo, 509 Iolanda, 651 Antikleia, and 2209 Tianjin) with different diameter sizes, and monitored them using a Global Rent-A-Scope CCD telescope over the Internet. I monitored each asteroid on three different dates for 2 hours each date, and received three sets of photometry images for each asteroid. I then sorted all of my images into different folders and used Minor Planet Observer Canopus Software to organize these images and turn my data into Light Curves. A Light Curve is a graph of light intensity over a period of time, and I used these light curves to estimate the rotation periods for each of my four asteroids. In conclusion I found that my hypothesis was supported and that the smaller the size of an asteroids diameter the shorter its rotation period. Below is a screen shot of Phaeo being analyzed with Canopus.
