Coral closing?

Hey guys, quick question. I forgot to turn my lights on before I went to school, so the night lights stayed on all day.. I just realized that and turned my lights on. My coral, can someone tell me what type it is, im totally spacing out. Is closed up.. is this just because of the lights? The water isn't an issue, And the salinity is right around 1.025. The glass is dirty and gross because it's been neglected for quite some time. The rest of my corals are doing quite well
