[AZ-Observing] Re: Any chance at Comet Linear this week?

Steve,

Not sure which comet you mean.  SMP10 shows 2 Linear comets that should/may
be visible this Thur: C/2003 K4, mag 8.9, which is rising in the east and
C/2003 H1, mag 12.4, which is setting in the west.  I guess the one that
sets around 7:30pm on Thursday as noted by Randy P is C/2002 T7, mag 0.5,
but I don't know if that one will be visible since its still pretty light
then and the comet is real low :)

In any event C/2003 K4 rises in the east about 8pm AZ time on Thurs and is
located about 12 deg below (east) Vega.  It is only about 9 deg alt at 9pm
when it is good and dark but should be easier around 11pm when it is about
30 deg alt.

C/2003 H1, which is awful dim at mag 12.4, is at about 32 deg alt at sunset
Thur located about 4 deg south of M48.  By full dark Thur, 9pm, this comet
is about 15 deg alt so it may be visible in a big scope.

The bright one, C/2002 T7, hits the horizon in the west about 7:18pm on Thur
and at that time the Sun is still fully above the horizon so I don't think
there is any chance it can be seen but I never tried anything like that so I
don't know for sure.  For whatever its worth SMP10 says C/2002 T7 sets at
19:20:34 on Thur, 5/20/04, 19:52:09 on Fri and 20:20:36 on Sat, slightly
different times than Guide.

If you are still trying SMP you can download Comet data from the internet
with a couple of mouse clicks and display them on the star map.  SMP also
displays very neat ephemeris tables showing pretty much any info you like
for any list of dates.
