I think it's been there for a few days. I was out recently with the pst tuning it for the sunspot and other surface features, then the prominences, then I got distracted by some mysterious dark channels leading away from the Sun's surface; I tried tuning to change them, changed eyes to see if I was 'seeing things', looked at the objective to see if it was clear, thought about reporting these channels on the forum, and finally figured what they were - the Sun had drifted close to some elm tree branches.
