Welcome to the BillWX
Upper Atmosphere Page!
(a.k.a. AURORA Page)
2010 Starts the next upswing in solar activity toward next solar maximum!
This is a completely NEW PAGE!
Here you will find interesting upper atmospheric phenomena visible over
NJ, or other parts of the U.S.
You may wonder...what "upper atmospheric
phenomena" can I see? Well, this page will not feature aliens, UFOs and
the like. Instead, here you will find interesting pictures of the upper
atmosphere..from the upper stratosphere to the exosphere. It is in
these areas that Auroras (or commonly "Northern Lights") are visible.
Satellites and space probes monitor the sun for storms that can send
charged particles into space. These fast moving particles of energy can
occasionally slam into the radiation fields and upper atmosphere of the
earth, causing auroras. When these storms become strong enough, we can
sometimes see these events over the skies of NJ. The year 2000 marks a
time of increased solar (sun) storms, in a solar cylce that
occurs every 11 years or so. The last time the sun became stormy was in
1989. However, the sun can unleash huge storms during non-peak times.
K-Index data: If the K-index on the
bar graph is higher than 7, auroral activity is more probable in the NJ
area (40 deg. N).
Note, if you're geomagnetic
latitude is higher, a lower number could result in activity. While
farther south, a higher number
is required for auroras to be
seen. The scale only goes to 9.
