Pardon double post, I also use the old mailing method.
Again, its always fun to have others join in on the chat, to compare notes, and realtime visual confirmation.
Here are the instructions on how to get on:

How do I get on the #SpaceWeather channel?
First you will need some way to connect to Undernet. On the Undernet website there is a web chat page you can use if you prefer not to install an IRC program. To get on our channel perform the next steps:
Fill in your preferred nick in "Nickname". Pick a descriptive nick, as no two people can use the same nick on the network. Optionally fill in an alternative nick if this is going to be the case.
In the "Your Favorite Channel" fill in #SpaceWeather.
In the "Channel" dropdown menu, scroll all the way down and select "Another channel".
From the server drop down, pick a option that is geographically closest to you.
Hit Connect! If all goes well you should be brought to the #SpaceWeather channel in a few seconds.
