STCE's Summer Games

The Sun has been quite active over the last few weeks (see e.g. this STCE newsflash), and is not expected to go quiet just yet. Nonetheless, just for those few brief dips in solar activity that may happen over the next weeks, here are five fun puzzles to keep you busy for a while. All puzzles are related to space weather (SWx), and the solutions can be found at the end of this article.

Good sources for more information on the words and acronyms used in these puzzles are the websites of the Royal Belgian Institute for Space Aeronomy (BIRA-IASB), the website of the Geophysical Centre of the Royal Meteorological Institute (RMI) in Dourbes, the ROB/GNSS website, the ROB/SIDC webpages, and the STCE space weather support pages on SWx acronyms and SWx classifications.

What's his/her profession?

You wouldn't say, but the name of each of these persons contains a profession closely related to the space weather domain. Can you figure them out?



SWx mix-up

While on holidays, a solar physicist slipped on a wet tile near the swimming pool. As a result, the contents of the suitcase got mixed up. Can you find which instruments are in this bag? They all are acronyms of instruments on board of operational space weather or solar satellites, and each contains 5 letters.
