Oh, also, the corona is a great place to hide. Its is Super hot and super bright, so your waste heat just gets drowned out in the solar noise. It is also a superhostile place, so no one comes looking. It is also super dull, so only a handful of groups watch the sun with any kind of regularity (people watching for CME, firewall, and solar researchers) and they do so with specialist equipment not really designed for searching out space whales.
So the corona is a great place to go on the run, and the Suryas are the best place to go in the Corona, because they are so weird no one bothers with them.
