[vsnet-campaign-v838mon 86] V838 Mon p magnitiude

Dear all,

I Have produced fotometric measures of V838 Mon on 4
images taken at 2002 02 02
with a 200 mm lens f/3.5 unfiltered, exposure 3 minutes on 35 mm film NPH
400


V838 MON 20020202.854 m1=9.02+-0.44
V838 MON 20020202.857 m1=9.47+-0.45
V838 MON 20020202.860 m1=9.05+-0.32
V838 MON 20020202.863 m1=9.26+-0.24

Comparison with my visual observation on the same nigth with a 20 cm SC
telescope unfiltered, f/10, 70x,
seem that I Have over estimated the magnitude (m1=7.8).

At my web page
http://digilander.iol.it/infosis/homepage/astronomia/comet.html
you can find the link at the images taken on 2002 01 10 and 2002 02 02 to
comparison.


Best Regards,
