Length of day governed by Earth's core processes
From the University of Liverpool , something I found interesting because a few years ago, former State Climatologist Jame Goodridge said he saw correlations between length of day and other…
Changes in Earth's gravity in relation to magnetic field measured
From the Helmholtz Association of German Research Centres Rapid changes in the Earth’s core: The magnetic field and gravity from a satellite perspective Annual to decadal changes in the earth’s…
Cool pictures from space of recent CME event auroras
Overnight on October 4-5, 2012, a mass of energetic particles from the atmosphere of the Sun were flung out into space, a phenomenon known as a coronal mass ejection. Three…
New study finds that a Carrington class solar event could cause global cooling of more than 3C
A paper recently published in Atmospheric Chemistry and Physics finds that “a solar proton event, if it took place in the near future with an intensity similar to that ascribed…
Aurora Borealis induced sounds confirmed – measured at 70m AGL
From Aalto University , something I’ve always wondered about but could never hear myself. They have a video of aurora, complete with sounds which follows below. I wonder if this…
NASA June 2012 Solar Cycle 24 Prediction
Compiled by Joe D’aleo WeatherBell via NASA MSFC The current prediction for Sunspot Cycle 24 gives a smoothed sunspot number maximum of about 60 in the Spring of 2013. We…
Solar cycle update for April – sun still slumping
Got a bit sidetracked earlier in the month, this is overdue for an update. Earlier we reported that Hathaway had updated his solar cycle prediction saying “…the predicted size makes…
NASA/Hathaway's updated solar cycle prediction – smallest in 100 years
…the predicted size makes this the smallest sunspot cycle in about 100 years (Updated 2012/05/01) From: http://solarscience.msfc.nasa.gov/predict.shtml The current prediction for Sunspot Cycle 24 gives a smoothed sunspot number maximum…
Geomagnetic data reveal unusual nature of recent solar minimum
From the American Geophysical Union weekly highlights: Key Points Minimum 23-24 showed recurrence intervals of 9.0 and 6.7-d Historical geomagnetic activity data show that minimum 23-24 was unusual The heliosphere…
NOAA: Strong Solar Eruption; Earth-Directed CME Likely
An X-5 class solar flare just occurred from region 1429, the large active sunspot group seen below. NOAA Bulletin from the Space Weather Prediction Center: 2012-03-07 01:03 Strong Solar Eruption;…
The sun is still in a funk: sunspot numbers are dropping when they should be rising
The sunspot number for February from SIDC is down again, to 33.1 Here’s the source of that data: http://sidc.oma.be/DATA/monthssn.dat So far, cycle 24 is significantly lower in SSN number that…
Homeland Security takes on The Carrington Event
While we worry about future threats like global warming, and present threats like Iran’s escalating nuclear program, the sun’s propensity for belching out monstrous solar flares (like the Carrington event…
Biggest solar storm since 2005
It is being called by WaPo “The Biggest solar storm since 2005“. The sun erupted late on January 22nd, 2012 with an M8.7 class flare. The Solar Dynamics Observatory captured…
Solar cycle update: sunspots down, Ap index way down
The NOAA SWPC monthly solar cycle update has been published here, and after a big spike last month, the sunspot count is down again. There’s an even bigger drop though…
Big CME hits earth, low latitude auroras possible
From the Rice University Spaceweather listserv Our space weather alert system is in level yellow, and the CME input of energy to the Earth’s magnetosphere still continues. So, if you…
New Geomagnetism Reference Page
Adding to the growing collection of reference pages available on the drop down menu is the latest offering that display aspects of geomagnetism. This is helpful for people interested in…
On the "Magnetic polar shifts cause massive global super storms" story
I’ve been avoiding this story (Magnetic polar shifts cause massive global super storms) for awhile, hoping it would simply die, but people keep asking me about it, and I see…
NRL Scientists Develop 3D Model of the Ionosphere F-region
From the Naval Research Lab, not our normal fare, but interesting for its uniqueness. The first global simulation study of equatorial spread F (ESF) bubble evolution using a comprehensive 3D…
First measurement of magnetic field in Earth's core
Earth’s internal dynamo generates average field in outer core 50 times that at surface A University of California, Berkeley, geophysicist has made the first-ever measurement of the strength of the…
