| Комментарий | July is normally a pretty cloudy time of year in these parts — summer monsoon — but lately it's been cloudy even by normal July standards. Last night was only the third clear night this month (and one of those was the 1st — right at full moon), and even this morning I had to contend with occasional clouds moving through. I did manage to get a visual observation of Comet 67P; it was faint, but not difficult to see in the 41 cm scope. I detected clear motion over an interval of half an hour. |
