[BAA Comets] cobs.si

[David Swan]

Thanks Peter, I've got it working. It can't cope with my latitude  + being so close to the summer solstice. It does not find any span of true night - that seems to be the problem. If I plug in a date in mid July everything works :) Anyhow, I really like the output. I can sort by magnitude and then can glance across at host constellations! David

Hi David,
I'm pleased someone has read my piece in the Comet's Tale!
You have to log into the COBS before you can use the Comet Observing
Planner, otherwise the site doesn't know where you are in the world.
The session start units are YYYY/MM/DD hh:mm and the session length is in
whole hours.
It works OK for me unless I enter a start time of 00:00hrs to 00:59hrs then
I get the Python script error message.
Limiting mag and min altitude are in whole numbers. I don't use the min
Solar and Lunar Elongation.
Hope you get it working and find it useful.
Peter

Hello,

I've registered with COBS.si, partly because - in his Tale article - Peter
said that he finds it very useful. I'm having some trouble with the Comet
Observing Planner - I'm getting Python script error messages. And it says
the sun is above the horizon at 2300? Whether UT or BST this is not right!

Is there a little quirk that I don't know about? In what units should you
enter the session time?

Thanks,

David Swan
