This question about atmospheric refraction of visible light was recently closed as off-topic because "it belongs on physics". While it would fit on physics I also feel that it is on-topic here, and should not have been closed. Much of atmospheric science is on-topic on physics but being on topic somewhere else does not make it off-topic here. Our scope exists independent of the other stack exchange sites.
Do we want a question like this here or do we want to turn them away? If they belong on physics instead of here, where is the the metric that decides that ?
I'd cast a reopen vote on the question but I do not want to unilaterally act without posing this to the community for consensus.
