NOAA has just notified us of a strong geomagnetic storm in progress. This occurred due to a large CME (coronal mass ejection) that occurred on February 9th. Again, I am unclear as to why NOAA/NASA waits three days to notify us. With SOHO on watch we know at the time it occurs and what direction the CME is heading.
Also, I am not sure as to how long a CME's hit will affect
power grids, satellites, and radio waves. I have put a call into Barbara McGehan
who is head of NOAA public affairs. Let's see what she has to say.
More on this later...
Strong Geomagnetic Storm In Progress...02/12/00
NOAA
A strong geomagnetic storm is in progress. The G3 storm conditions
commenced following the detection of a shock at the Earth's magnetic field at
11Feb/2353Z. It is likely that this geomagnetic storm originated from a solar
flare and associated coronal mass ejection that occurred on 9 Feb at around
2000Z. This level of disturbance routinely causes power grid fluctuations, increased
atmospheric drag and surface charging on satellites. Intermittent navigation
system problems, signal
fade of high-frequency (3-30 MHz) radio signals and auroral displays at mid-latitudes
are also possible. Numerous auroral sightings have already been reported in
New England.
Data used to provide space weather services are contributed by NOAA, USAF, NASA, NSF, USGS, the International Space Environment Services and other observatories, universities, and institutions.
