Just an update, David Moore in Ireland spotted the comet easily in 20x80 binoculars on january 1 and estimated the comet at magnitude 2.5-3.0. This observation was made with the comet just 3 degrees above the horizon in very bright twilight (sun 9 degrees down).

Scott, make sure the sun is obscured by a building and ensure there is no sunlight shining into the tube (it will scatter light and greatly reduce contrast). John Bortle determined mag -1.5 as the minimum brightness for daylight detection near the sun, but it takes some practice to achieve this. In the nineteenth century there were a few skill visual observers that were able to follow these objects close to the sun (these same observers followed planets through solar conjunction), but few people do this these days.
