Bossmo
Observatory is located in a suburban area near Mo i Rana, Norway (at 66°
20' 27'' north and 14° 06' 54'' east). It houses a 25 cm SCT @ f/4 with a SBIG ST-7 CCD camera and Schuler BVRI
filters.
It is used for photometric studies of variable stars, mostly Delta Scuti stars, but also cataclysmic variables as part of the CBA network, or others as requested by e.g. the AAVSO. All observations are, with time, submitted to the AAVSO International Database, and most of the time series are available under the observation log section. I also use the RAS Observatory in New Mexico. During the bright northern summer, this is the only way for me to observe. I will try to update the web site with current activities, methods used for reducing and analysing data, equipment checks and various projects. Geir Klingenberg |

Photometrica
Photometrica is a collaborative effort between GRAS and myself. It's a web-application that lets you do photometry of CCD images taken with the remote GRAS telescopes. Customers of GRAS controls the telescopes through the browser, and now Photometrica lets you analyse the images as they are downloaded from the camera. So all you need in order to do photometric research is a browser!

| WinWWZ This is a software tool that I helped AAVSO with, by converting their analysis engine to C++, and by adding a new user interface to it. From the AAVSO web site: "WinWWZ is a Windows XP-based tool for period analysis of variable stars or other time series data using wavelets. It is designed to work with data from the AAVSO International Database downloaded via the official form to download data but will work with most generic time series data sets and supports flexible input formats."

| AIPImport AIPImport is a simple tool used to display and analyse time series photometry produced by AIP4Win (version 1 and 2). It is designed to ease the work associated with these files, and to give a more detailed look at the data than AIP4Win does. You can plot graphs of the variable and the check star, smooth the light curve, and merge several AIP files. It also saves the data in AAVSO or CBA format, and exports an image of the graphs to the clipboard. All graphs on this web site has been made using this utility. I made this tool for my own convenience, but feel free to download it and use it if you like. |

- Whole sky photometry
- Photometrica
The observatory was built in 2003. It has a standard roll off roof construction, and is remotely controlled from the nearby building. All that has to be done outside is opening the roof (and shuffling snow ...). It was built to provide quick and easy access to the equipment whenever the sky is clear, which is essential in this costal climate where the moments with clear skies may be brief. Also, doing photometry requires a CCD camera, PC etc., and without the shelter of the observatory this would be nearly impossible due to the amounts of snow we usually have here. And it would be very unpleasant work in -20 degrees Celsius ...
