[vsnet-alert 14420] Re: [AAVSO-DIS] [AVSON] Re: AAVSO Sequence for TCP J14250600-5845360

[Rob Kaufman]

Hi all - I've followed this reddened object for three consecutive nights
and while DSLR estimates are pretty useless I'll give them anyway because
there doesn't seem to be a lot of photometry coming in.  I've revised my
first observation (5 April) using the AAVSO sequence.  Hope these are of
some interest, even in terms of relative brightening.

Unfiltered, from RGB:
TCP J14250600-5845360    2012 5.544 April    10.2  (9.6, 10.2)
TCP J14250600-5845360    2012 6.597 April     9.8   (9.6, 10.2)
TCP J14250600-5845360    2012 7.392 April     9.6   (9.6, 10.2)

Green channel (usually a fair approximation to V-band):
TCP J14250600-5845360    2012 5.544 April    10.4   (10.2, 10.6)
TCP J14250600-5845360    2012 6.597 April    10.0   (9.6, 10.2)
TCP J14250600-5845360    2012 7.392 April     9.8   (9.6, 10.2)
