I improved my reading of the star field and retook a lower magnitude reading at 9.7; 10.2 apparent. Conditions were the same as yesterday, but seeing was worse do to wind. (Decided yesterday's reading of 9.9 was in error.) Object: AAVSO1811-30N Sgr 05 #2 Date: 2005.07.13 7:04 UTC 2453564.7944 Magnitude measured: 9.7 true mag.(visual, extinct. adj. mag); apparent 10.2 (visual) AAVSO reported raw ranges for JD 2453562-64 are: 9.1-9.5 - mostly CCD through J-band filter reports See << http://www.aavso.org/cgi-bin/searchcharts3.pl?name=n%20sgr%2005%232
Seeing: A-III; A-II on 6/13. Alt_object: approx. 18° Magnitude trend: Nova continues to dim from v8.0 on JD2453559 (approx. 4 days), but is easily visible with small aperatures (70mm) in low light polluted skies. Based on the AAVSO light curve trend, that is a linear rate of roughly 0.3 mags per day ( (9.5-8.0)/5) ). The later setting moon will make observations increasingly more difficult until the sky is washed-out around July 15. Observing point: Little Mountain Pass, 10 miles east of Salt Lake City, Utah, Latitude N 40.8, Longitude W 111.9, Altitude approx. 7700 ft. (2347 meters) Scope: 20x70 binoculars, parallelogram mount, 1.5° x 1° TFOV. See prior 7/13 post for other details. - Enjoy Canopus56 (Kurt) __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
