[VHFcontesting] [222Activity] [yccc] Earth-Directed Explosion on the Sun

[Bill Olson]

Hi Dave and all, so the K index is already up to 5 and appears to be headed UP yahoo.. I will be monitoring 222 and 2 meters today and tonight. Can I assume Au  activity is "old school" i.e. actual CW, or is there some digital mode that we are using for Aurora now? Frequencies? Chat on ON4KST 144,432 region 2 ?

Hi Marshall

I have a table front and center for live bluegrass music Sunday, and the music ends at 0000 UT  or 8 PM. EDST. I will be tearing home and start monitoring 222 MHz in hopes of any possible aurora. I should be home by 00:30 UT Sunday evening. Now, normally, things don't work out when you think they will, but that does not mean that you should not pay attention!  I remember corresponding with Ed Tilton after a fantastic aurora and he mentioned that you don't get conditions like that every day. Within a few more days, we had an aurora to end all auroras and I was up all night working AU buzz and Au Es until dawn.  You never know!!

The grass is bluegrass in Kentucky.

Just a heads up.  If another aurora shows up, please check 222 MHz this time. It might be open. The big AU in late March sent the K Index to 7 or so, and 222 was alive and well. The CME speed is about 580 km/s  and it is projected to hit Earth at 0000 on 24 April. That is 7 PM on early Sunday evening. I will be ready and have my generator all gassed up (or dieseled up)  I am supposed to be out for dinner and bluegrass music at 2200 UT but Auroras are more rare than bluegrass.

A CME is heading straight for our planet

AN EARTH-DIRECTED EXPLOSION ON THE SUN: Yesterday (April 21st), a large magnetic filament snaking across the sun's southern hemisphere exploded, hurling a CME straight toward our planet. Estimated time of arrival: April 24th. Minor to strong geomagnetic storms are possible when the CME strikes.
