Object name: UGC06446
UGC 6446 is a low surface brightness, face on spiral in Ursa Major just under the bowl of the Big Dipper. Redshift puts it about 38 million light-years distant but Tully-Fisher measurements put it at about 51 million light-years. It is sometimes considered part of the Northern M109 Galaxy Group. If so that would favor the 51 million light-year distance so I'll go with that. That would make it about 55,000 light-years across its longest diameter. I'm measuring this diameter at 3.7 arc minutes while NED lists its size as only 1.25 arc minutes. Others say diameters up to 2.8 minutes. Yet I'm quite confident at my measurement. I can't explain the difference.
