[vsnet-chat 7129] Re: [cvnet-discussion] Re: [vsnet-alert 8475] V841 Oph fainter than usual?

[Keith Geary]

Thanks for checking that out Bill, this one is still the 'oldest confirmed' known nova, so there's a bit of history there!
I had a look with my 8 inch early this morning, I too used the aavso 'f' chart, I still need a bigger scope!
Maybe we should look at this one more often.

OPHV841  July 02.981      <126

  Keith, 

  Interested by your post, I imaged V841 with our club's CCD camera and
  V filter.  Using the 14.5 comp star from the AAVSO's Preliminary f
  chart, I got:

  V841 OPH    JUN 30.2042     2453551.7042      13.64V   DIL

  The chart has the magnitude range as 4.2-13.49V, so this doesn't seem
  to be far off the mark.
