Laramie Aurora Visibility Alert (LAVA)
I just did discover this site/service run by Brian Rachford
Brian proives e-mail alerts to viewing opportunities for the Aurora Borialis from Laramie!
Please, visit his site, the LAVA homepage for much more info and to subscribe

Solar X-rays: Status
Geomagnetic Field: Status
From maj.com

The Solar X-Ray Monitor
The X-ray Solar status monitor get's the current status from the NOAA Space Environment Center server
The previous 24 hours of 5 minute Long-wavelength X-ray data from two satellites (GOES 8 and GOES 10) is analyzed, and an appropriate level of activity for the past 24 hours is assigned as follows:

= Normal: SolarX-ray flux is quiet (flux <= 1.00e-6 W/m^2)
= Active: SolarX-ray flux is active (flux >= 1.00e-6 W/m^2)
= M Class Flare: An M Class flare has occurred (flux >= 1.00e-5 W/m^2)
= X Class Flare: An X Class flare has occurred (flux >= 1.00e-4 W/m^2)
= MegaFlare: A 'monster' X-ray event has occurred (flux >= 1.00e-3 W/m^2)

The Geomagnetic Field status monitor
The Geomagnetic Field status monitor gets the current status from the NOAA Space Environment Center server
The previous 24 hours of 3 hour Planetary Kp Index data is analyzed and an appropriate level of activity for the past 24 hoursis assigned as follows:

= Quiet: the Geomagnetic Field is quiet (Kp < 4)
= Active: the Geomagnetic Field has been unsettled (Kp=4)
= Storm: A Geomagnetic Storm has occurred (Kp > 4)
