I have never heard of that, and it is in direct violation of the rules. If you are concerned, contact the competition director or the event supervisor. If you don't get a response, print a copy of the official astronomy rules and take it with you. If they still say no at the competition, submit an appeal, and probably tell the forums. I don't have any experience with this type of stuff, but I'm sure others in the forums could help you.
To be fully honest, you have almost no reason to worry. I really don't think that the rumor has any validity at all, but still, I'd rather you were safe than sorry.

Same as PM2017 (take a copy of rules if worried, but it shouldn't this shouldn't be an issue). One thing, though, is that posting on this forum likely won't help directly (though, we'll definitely make it loud and known that supervisors should never do that...that said, that probably still won't solve much). Contacting the tourny director and politely pointing out the part of the rules to the supervisor should always be the way to go (I know I would love it if competitors told me if I am mistaken on what time an event should start or communicated with me...). If people don't listen to reason, then it sounds like it'll be tough, but I wouldn't worry too much about this issue.
There is one case off the top of my head where no laptop was allowed, though it wasn't because competitions were lower-quality or something. A few years ago I noted North Carolina didn't allow laptops, but they do now. States can come up with state-specific rules clarifications and post them on their website. For example, some add to the lists used for ID events or make trial events count. I'd be curious what states / supervisors still don't follow allowed materials, though.

Georgia does not allow laptops for Astronomy, although regional event supervisors are frequently unaware of this. The event was excluded from scoring due to some inconsistency on this point at our regional. Interestingly, last year the state tournament specifically allowed laptops.

Ah that sucks. I got my info from someone who did astro at my school last year so this must be what they were referring to. Looks like I've got three days to start burning through some ink now...
Thanks for the heads up, though.
Hello, I'm new to Astronomy and was wondering what the standard equation for Classical Cepheid Period-Luminosity or Period-AbsoluteMagnitude relationship is? From my searching so far, I've found three different formulas:
M = -2.43(log(P)-1)-4.05 (This is just wikipedia's equation without the margin of error)
M = -2.78log(P)-1.35
M = - [2.76 (log10(P) - 1.0)] - 4.16
Which Period-AbsMag formula is typically used on Astronomy tests? Thank you!

Typically, the first is the most commonly used. Though, sometimes if the test writer is really good, they'll give you the equation they want you to use to avoid any confusion. The relationship also varies depending on what band you're in.

Ok, thank you!!!
If they don't definitely show your work (you should be doing this anyways...), so that they recognize that you might have had a different equation than them.
Can someone help me with 17e on this test? I've tried using M_a + M_b = a^3 / p^2, but I don't know what to do to find a: https://scioly.org/tests/files/astronom ... h_test.pdf
Also, if the variable a is intended to be the semimajor axis of a planet-sun system, how does that apply to different types of binaries (i.e. venn diagram like binaries or concentric binaries)?

I remember struggling with that exact question... You have to find the circumference by multiplying the tangential velocity by the period. You can find each of those two quantities from the diagram.
