Guys,

I have a test version of a little web app that I'd like you guys to help me test.

Its an app which calculates the transit times (in UT) of the GRS (Great Red Spot on Jupiter. If this works out I have a whole pile of such ephemeris type scripts ready to deploy.

webtreatz.com/component/option,com_wrapper/Itemid,83/

Please don't share this address outside of these boards just yet as this is very much a beta test.

Thanks for any feedback.

Update - 21 June 08

I've added a Sunrise/Sunset/Twilight calculator;

Hi Dave,
looks great !
One thing if possible, do the dates gave to refresh back to Jan1 2008 after you run it?
Why bother with the password thingy.
Would a button showing the next 7 days be useful? like the ISS passes in heavens above.
The only thing now is will the weather allow us to actually test it anytime soon. :(

Good point.

Why bother with the password thingy.


The calculations take up processing time on a hosted server, therfore I don't want messers clicking like mad for no good reason. Also to prevent robots from farming the data. Also helps limit 'denial of service' attacks.

Would a button showing the next 7 days be useful? like the ISS passes in heavens above.


Excellent idea.

The only thing now is will the weather allow us to actually test it anytime soon. :(


I'm actually pretty confident about the timings. It's all of the sort of useful suggestions you mentioned above which I really want to hear about

Dave G,

This is great! I've just used it. It's a nice handy calculator.

What about the second red spot and the more recently manifested small red spot? ( for fussy astronomers like me).

Thanks for sharing this useful tool.

See I knew this place is awash with great ideas. Very little change is needed to predict times for other features.

Nice work Dave.
I think the suggestions above are very good and I can't add much more than that at this time. I just cross-checked it with todays times from the S&T page and it's looks pretty accurate.

However, your calculator allows a month's worth of calculations, which is very handy.
Thanks for sharing it here.
