Welcome to the Home Page of the Nordic Mars Observers (NMO), an amateur astronomical group devoted to the study of Mars for planetary observers primarily of the Nordic countries. All types of observations of Mars are welcomed. Most studies contributed are visual, but photographic, CCD and video observations are very welcome. The work is coordinated and analysed by Johan Warell who gladly accepts all contributions by either traditional mail or e-mail. See further Contributing observations.

The work of the group is performed according to international standards according to the European tradition. Standard Wratten glass colour filters are employed for feature discrimination. Visual observations are documented on the NMO Visual Observation Report Form, with a European standard Mars disk size of 50 mm. Ample space is provided for feature intensity estimation using Wratten filters.

International cooperation

Cooperation and exchange of data with other international Mars observational groups is a vital part of the NMO program. These include the Mars Sections of the British Astronomical Association (BAA), the Association of Lunar and Planetary Observers (ALPO) and the Oriental Astronomical Association (Communications in Mars Observations, CMO). NMO observers wishing to communicate observations to these societies are asked to do so personally.

The aim of the NMO web pages is to successively present contributed observations as well as providing helpful information for the observer. Excellent current summaries of Mars observations are provided by the BAA and CMO. A wide range of internationally contributed observations are presented on the MarsWatch 1998/9 web site.

Observations are welcomed to the Coordinator for publication on the NMO homepage and subsequent analysis. Please contribute observations in the form of photocopied observing forms to the ordinary mailing adress. Please make sure all details of the drawing are represented on the photocopy. If you have access to a scanner, a better option is to scan the 50 mm observation disk box only at 150 dpi and 8 bit greyscale, and mail it to the coordinator together with a filled-in data textfile for the specific observation, according to the format of the observation html-document file.
