Are any states allowing star charts......
In MD regionals we had to put our notes away because we had a star chart on it.
Are any states allowing star charts part of your notes.....

please reply

They let us use a star chart at our regionals in AL...

Hey, if you can fit a labeled chart in your notes it is legal. 2 pages notes in ANY FORM from ANY SOURCE. Your MD Star ES needs to read the rules.

I've done this event for invite and Regional comp. My notes were horrible, because I didn't want to be in this event, and I was busy with other events. My school is going to state (for the 6th consecutive year ) in 6 weeks and I need better notes. Does anyone know what I should include in my notes? I've competed, but I'm still lost.

Anything you don't know. A map of the constellations is always a good idea; they tend to use Rey's Constellations, from what I've seen. You should have multiple pictures of all the DSOs, make sure that you have some thermal imaging and x-ray pictures. For the notes, it might be good to just make a chart for the stars, with the magnitudes (absolute AND apparent), luminosity, temperature, constellation, etc.

Thanks! Wow, I don't even know what you are talking about for half of the stuff.

There are several different systems of constellations: Zodiacal, Astronomical, and Rey's. Rey's is the easiest to ID and better to use; however, there are some charts that are a mix of all three systems. I have a chart like that for my star chart--works very well, it makes everything much easier to ID with just one chart.
DSO=Deep Sky Object. You should be able to search up and find everything via Google Images (ex. search "cassiopeia a x-ray")
Magnitude--basically how bright something is. Absolute is the true brightness. Apparent is how bright it seems from Earth. The lower the magnitude, the brighter it is.
Luminosity--this is based on 1 Sun=1 Luminosity. So a star with 4.5 luminosity would mean that it is 4.5 times as bright, or luminous, as the sun.
Temperature--self explanatory.
Constellation--the constellation each of those stars are in.
Also, include right ascension and declination.
And spectral types too...and distance from Earth. All good things.

Anyone have good sites for hr diagram? It was the one thing we missed at regionals.

[tying15]

We put down O as the hottest star in the Spectral Classification of Stars and they counted that wrong. What is the right answer?

[foreverphysics]

Well, O is the classification of the hottest stars...but that's normal classification. Is it possible they were using Yerkes' Spectral Classfication? If so, the answer is Ia.
