Everybody - not just members, and not just imagers - are strongly encouraged to submit reports by way of images, sketches, or even without any imagery. You can come up and give a verbal report about the conditions you observed under, the details of the equipment you used, what you'd had for dinner, and of course a description of the object as you observed it! Be sure to send them to me for inclusion in the next meeting at meetingchair[at]ottawa.rasc.ca

I still encourage more people submit reports than did this past month -- I encourage everyone to participate, not just imagers! You can submit reports by way of images, sketches, or even without any imagery, you can come up and give a verbal report that perhaps includes the conditions you made your observations under, and the details of the equipment you used -- and of course a description of the object as you observed it! Be sure to send them to me for inclusion in the next meeting at meetingchair[at]ottawa.rasc.ca
