Planetarium New Reader Registration
Planetarium is in weekly instalments starting from when you register. If you register now you can submit solutions to the puzzles in part i but you won’t be granted access to part ii until next week.
If you’ve already got a reader-name for Planetarium, you should log in here instead.
An RSS feed is available after you’ve logged in.
Give yourself a reader-name, so that Planetarium can identify you when you visit.
Choose a password that is not easy to guess, but that you won’t forget (the password is case sensitive). Keep your password secret. We do not re-issue forgotten passwords — if you forget yours, you’ll have to go right back to the start.
Planetarium uses a cookie to identify you when you log in. The cookie is deleted when you logout, or close your browser.
Planetarium can automatically remind you by email if you forget to log in for over a week, so you don’t miss any instalments. We don’t mind if you leave your email address blank, but of course if you do that you won’t be sent a reminder — but if you have an RSS reader you don’t need email reminders anyway. Afterwards, your email is deleted. See the FAQ about email to be reassured.
After you’ve registered, if you let a few weeks elapse without logging in, your reader-name will expire. Just make sure you visit every week, and you won’t have to worry about this. You will be granted access to a new instalment of Planetarium every seven days, starting from registration (give or take a few hours).
There is a lot more information in the extensive Planetarium Frequently Asked Questions.
