The word "observably" is an adverb that means capable of being seen or noticed, especially by the use of the senses. It often implies that something is visible or perceptible to the human eye or, more broadly, to the senses. For example: "The stars in the night sky are observably different from those in the day."
I'm afraid there is no such word as "observantine". It's possible that it's a typo or a made-up word. If you meant to type a different word, please let me know and I'll be happy to help you with its meaning.
