                  Dear all,
                  Three evenings of clear weather:

                  C/2011 L4 (PANSTARRS)

                  2013 Mar. 21.795 m1=$S 2.8, Dia=3', DC=8, dust tail 1.1 deg in PA 40, 10x56B.
                  Altitude comet: 9.4 deg.
                  Comparison stars: 31 del And = 3.40 (Alt. 17.7 deg.). 99 eta Psc = 3.71 (Alt. 12.8 deg.).
                  Using Summer table because of Relative Humidity of 82%. Temp. -1.4 C.

                  2013 Mar. 26.803: !m1= 3.5, Dia=3', DC=7/, tail 1.5 deg in PA 20, 10x56B
                  Altitude comet: 11.7 deg.
                  Comparison stars: 31 del And = 3.40 (Alt. 13.6 deg.). 99 eta Psc = 3.71 (Alt. 8.2 deg.).
                  Using Winter table because of Relative Humidity of 60%. Temp. 0.0 C.

                  2013 Mar. 27.803: m1=! 3.7, Dia=3', DC=7, tail >1.5 deg in PA 15,10x56B
                  Altitude comet: 12.4 deg.
                  Comparison stars: 31 del And = 3.40 (Alt. 13.2 deg.). 30 eps And = 4.44 (Alt. 11.8 deg.).
                  Using Winter table because of Relative Humidity of 50%. Temp. -1.9 C.

                  Comet seems brighter in 6.5 x 44B. Probably because of interference of the dust tail.

                  All observations in Moonlight and at the end of the Nautical Twilight from the City of Groningen, The Netherlands.

                  ICQ format.
