| Comment | I did not have the best sky conditions tonight (thin cirrus clouds moving through), but I did — finally! -- pick up this comet. I followed it for about 45 minutes, and motion was obvious within just a few minutes. May 18.17 UT, m1=14.1, 0.3' coma (I would actually put it closer to 0.25', but I don't want to imply a precision of 0.01') (41 cm reflector, 229x). The comet did appear slightly non-stellar, but especially with the conditions I couldn't tell much else. |
