Default A great view of Mars in August (farewell)

With all due respect, I don't for one moment think that Mars could appear
the same size as a full moon. I asked for some advice on this, as this after
all is a technical ng, and in moments someone very kindly on this ng passed
on the URL to me, which explained what was going on. I have since forwarded
that URL on to the person who sent me that email in the first instance, and
she has since replied saying thank you. That's all there is to it. I am
sorry that anyone was annoyed by that:-(
I'll take this opportunity to say that this is be my last posting on
this ng, as it appears that my contributions regardless of whatever I wish
to say, are obviously no longer welcome:-(


Oh no, not the burning martyr routine please......

You know damn well your weather related posts are welcome here, just
not the off-topic stuff which you seem to be posting with increasing
regularity, despite repeated (polite) requests for you to desist.

However if you want to go off and feel sorry for yourself then that's
your choice.

I read the first posting and found nothing wrong. I remember that
Mars' diameter is given as 25 arcseconds. If one looks through a 75 X
telescope the angle becomes 1875 arcseconds or 31 minutes, the
diameter of the moon as we see it with the naked eye.

Am I mad or am I?

Sytze, (80 since a couple of months ago)

Gavin was quoting figures that may have been true in 2003, but they
are certainly not this year. The apparent diameter of Mars is no
greater than 14 arcseconds this August.

Best wishes, Roger


Thank you Roger.

Indeed, in the "Sterrengids" -Starguide- 2003 the apparent diameter of
Mars is given as 25.11" at august 28, in 2005 it is much less.
I shouldhave consulted the books first.
What remains is a half moon, so to say ;-)

Regards,
Sytze
