On this page we present the observations of the comet 2P/Encke, made on the 23th of October 2003. A very fast reduction has been done.
Observation
Preprocessing Time: 23th of October 2003 from 22h39m57s to 22h48m51s. Instrument: T62 with a 2x reducer CCD: ST8ex working in binning 3x3 Exposure times: 15sec. The reduction has been done based on the following stars: GSC 2806 2181 RA:00h58m32.378s DEC:+42°19'24.06" MAG:15.01±0.39 GSC 2806 1497 RA:00h57m59.623s DEC:+42°17'57.01" MAG:14.17±0.40 The comet was taken as a star to determine its magnitude, so the we only measure the nucleus: The average magnitude was 15.08. Astrometric reduction Time: 23th of October 2003 at 22h39m57s - these images are not made for astrometric reduction, therefor the clock of the controlling PC was not adjusted to an atomic clock. Deviations of 1 minute could be possible. Sorry... Instrument: T62 with a 2x reducer CCD: ST8ex working in binning 3x3 Exposure times: 15sec. The reduction has been done based on the following stars: GSC 2806 2181 RA:00h58m32.378s DEC:+42°19'24.06" MAG:15.01±0.39 GSC 2806 1497 RA:00h57m59.623s DEC:+42°17'57.01" MAG:14.17±0.40 GSC 2806 1619 RA:00h58m35.112s DEC:+42°22'17.79" MAG:14.17±0.39 GSC 2806 1369 RA:00h58m32.008s DEC:+42°20'44.62" MAG:13.42±0.39 GSC 2806 1697 RA:00h58m00.828s DEC:+42°17'24.93" MAG:14.98±0.40 GSC 2806 1483 RA:00h57m56.097s DEC:+42°20'06.00" MAG:13.81±0.40 We find the following result: ALPHA = 00h 58m 23.000s DELTA = +42° 19' 46.35" C2003 10 23.94441 00 58 23.000 +42 19 46.35 |
