Yesterday my colleague had a chance to use our Coronado SolarMax II telescope for the first time on her own. It had been thought that maybe I should introduce the telescope to her beforehand so she'd have a better idea of how and why it works. However I was in a hurry to leave work early and hoped that as an astronomy student she'll be fine.

However yesterday, on my day off I get several calls, where she's inquiring about the telescope and to top it off a very excited colleague calls me saying "this is so cool - there are two rings, I've never seen an image like this before with this telescope. I wish I could take a picture. Can you come here? Please, please, PLEASE hurry here!"

So I, having checked the latest image of the photosphere and whether there are any sunspots, I think - okay, maybe there's something interesting going on, and she's just not explaining it right. If it's rings, it's likely to have something to do with the telescope - right?

So I leave home, racing to work not having had time to even have breakfast yet. The telescope is all set up outside, as I'd asked her to leave it the way it was, and another colleague is keeping an eye on it. And then he shows me a picture of what they were so excited about - they had been observing without the eyepiece and were able to see a little bit of the inside structure of the telescope together with a tiny sun. Nothing extraordinary. But I wouldn't have thought they'd forget to use an eyepiece :)

The Lyrid meteor shower will be active this year from April 16th to April 25 th with the best time for observations is on around April 23rd.

The beginning of the active time for this meteor shower happens to be when the Moon is just a thin crescent and sets early, and during the culmination of the meteor shower it sets a more than an hour after midnight - so it's a great time for seeing some meteors weather permitting.

Electricity and Magnetism: New Formulation by Introduction of Superconductivity by Teruo Matsushita

Electricity and Magnetism is a crucial part of any undergraduate physics course at colleges and universities and one that often times separates the students into who will graduate and who will not.

Electricity and magnetism is fascinating if you spend enough time actually learning it - just a lecture course normally wouldn't be enough, and you have to work hard with a textbook. Although there are probably few lecture courses that teach electricity and magnetism with this formulation, students would benefit from looking at the subject from a different angle, where you get a better understanding of the interplay between electric and magnetic fields.

The textbook is quite interesting right from the beginning, various exercises and worked examples help set in the topics covered and if needed you can consult the appendix for some of the mathematics you might need if you get stuck with something you've forgotten.

If you've previously gone through an electricity and magnetism textbook that uses the more classical formulation, then this one will either seem like too much or like a fresh new breeze and very exciting.
