Long duration C1 flare+Prominence lift off

http://cesar.kso.ac.at/main/last_Ha.php

Still three regions visible.
Largest region so far: 1575 which is a EHO Beta-Gamma type group at 260 millionths in size, which is slightly down from the previous day.
Region 1577 increased from 20 to 100 millionths and is a DAI Beta type group.

 

Happy Autumnal Equinox

Happy autumnal equinox today for northern hemisphere residents

 (vernal for those in the southern)
occurs @ 10:49AM EDT/14:49UT

 At 14:49 UTC, 2012 is the earliest the September Equinox has occurred since 1896, but will be beaten by 28 minutes in 2016!      

Region 1573 reappeared yesterday after two days without visible spots
All groups decreased in size yesterday. The largest region is still region 1575 and is still a EKO Beta type group.
No C class solar flares took place yesterday. The largest solar flare was a B8 peaking at 1221z from region 1573. Only occasional C class solar flares are expected today

Sunspot 1520 LDE Solar Flare In Progress - July 17, 2012

Starting today at around 13:15 UTC a LDE (long duration event) solar flare began around sunspot 1520. This event is still in progress at this time with it reaching a M1.7 level thus far  

 

There was a large bright CME seen in association with this LDE Flare

It is unsure at this time if this CME will be geoeffective or not

CME from July 12th X Flare Has Arrived

   Here comes the CME! OK OK we have something here everyone. After waiting all night, the 1st signs of the much anticipated CME from July 12, 2012 X flare are now showing up on ACE. A mid latitude aurora watch is in effect

Ace Solar Conditions @ 09:22 UTC-
July 15, 2012
Solar Wind Speed : 578.7 Km/s
Density 1.1
Bz -16.0

   Space Weather Message Code: ALTK06
Serial Number: 287
Issue Time: 2012 Jul 15 0754 UTC

ALERT: Geomagnetic K-index of 6
Threshold Reached: 2012 Jul 15 0748 UTC
Synoptic Period: 0600-0900 UTC
Active Warning: Yes
NOAA Scale: G2 - Moderate
Potential Impacts: Area of impact primarily poleward of 55 degrees Geomagnetic Latitude.
Induced Currents - Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms.
Spacecraft - Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible.
Radio - HF (high frequency) radio propagation can fade at higher latitudes.
Aurora - Aurora may be seen as low as New York to Wisconsin to Washington state.

Solar Wind Speed : 605.7 Km/sec
Density: 29.8.3
Bz: -4.0

UPDATE @ 02:41 UTC July 15, 2012

Solar wind speed, density and the Bz have been fluctuating up and down since this CME arrived earlier today. Right now, we see another rise in wind speed and density and the Bz just dipped south.

ACE Solar Conditions @ 02:31 UTC-
July 15, 2012
Solar Wind Speed : 660.6 Km/sec
Density: 12.0
Bz: -9.6

Everyone please keep in mind that this CME has only arrived at 17:28 UTC July 14

That was around 9hrs ago. This CME is forecasted to remain geoeffective for around 30hrs

We still have many hours left before this CME has completely passed by Earth.

We will keep watch for any significant changes and report accordingly as to any changes :) 

Added ACE data update:
Solar wind speed just jumped to 759.1 Km/sec
