A couple of minor Solar Storms from Tuesday-Wednesday

Post by grimble_cornet » Thu Apr 14, 2016 9:48 am

As requested by Alexandra......

Here is what my magnetometer recorded on Tuesday-Wednesday (12th-13th April):
Magnetometer 12-13th April 2016.jpg
The first event which peaked at about midnight on Tuesday was a minor (G1) geomagnetic storm resulting from an increase in the solar wind speed passing over the Earth. It produced some minor auroral displays if you managed to avoid the cloud :evil:

The second event which peaked at about 9pm on Wednesday was a slightly more active, but still G1, storm caused by a high speed stream flowing from a series of 'Earth directed' coronal holes.

Many thanks to Stu for help constructing the magnetometer and for the use of his excellent software. It is great to have a method of observing the sun which is not degraded by cloud, rain, poor seeing and the dreaded jetstream :evil:

Nice observations there Mike! I thought about getting home early this aft to maybe try a full disk, but then a few minutes later, even though it was sunny, it was raining too...

Yeah, I know the feeling; I was keeping my fingers crossed for much of the day but only managed a few tantalising glimpses of the sun :roll:
