Update @ 22:16 UTC July 12, 2012

After review of today's CME on STEREO A and STEREO B, we set the calculated  time of arrival around 06:00 UTC July 14th (+/- 4hrs.)
Moderate to severe geomagnetic storm activity reaching G2-G4 (Kp 6-8) will be possible at that time. We will continue to review data and will report on any changes we may find.

## Alert Summary:

Type O CME detected by STEREO-B COR2.

Start time of the event: 2012-07-12T16:54Z (STEREO-B-COR2).

Based on rough estimates (only STEREO-B-COR2 images are available currently) the CME parameters are:

Estimated speed: ~1400 km/s.

Estimated opening half-angle: ~ 70 deg.

Direction (lon./lat.): -6/-17 in Heliocentric Earth Ecliptic coordinates.

The CME is associated with the X1.4 flare peaked at 2012-07-12T16:52Z (see alert 20120712-AL-001).

All spacecraft between the source region (AR 1520 - S15W01) and Earth (including MEO, GEO and other high-altitude orbits and high-inclination LEO) can be impacted. Updates on this event will be provided when available


* As a result of todays X flare and associated CME there is a S1 solar radiation storm in progress

Update from SWPC:

2012-07-12 19:31 UTC Solar Eruption Today -- Further Analysis

The R3 (Strong) Radio Blackout today at 12:49 EDT (1649 UTC) was accompanied by an earth-directed CME. Hampered by limited observations of the event, SWPC forecasters are now anticipating the passage of the CME around 1:00 a.m. EDT, Saturday, July 14. G1 (minor) Geomagnetic Storm activity is expected to then ensue through the rest of the day. An S1 (minor) Solar Radiation Storm is now occurring, also a consequence of the flare/CME. The parent active region, NOAA 1520, appears to have retained its ability to erupt, so watch for more

Expected CME Update:
this is my unofficial view
this because we have had so much activity with flares and CMEs that we would have to factor in Quantum entanglement.
We have talked about this in extent in the past here.
It is not just about the earth direction and size of a given CME, But there is a LOT of physics that plays into all this as well! Because of this, i do not have enough time to research into all the data and calculations before the arrival of the following CMEs.
So here we go :)
 
the ENLIL model is showing a hit from 2 CMEs starting around 00:30 UTC July 8th
http://www.swpc.noaa.gov/wsa-enlil/
right now, it is 21:53 UTC
That would make the shortest ETA for the 1st hit to be somewhere in around 2-3 hours (8-9 pm EST)
these CMEs would be 1 from July 4th
the 1st one as we see here @ 01:24 UTC July 4th
http://stereo-ssc.nascom.nasa.gov/browse/2012/07/04/ahead/cor2/1024/20120704_012400_d4c2A.jpg
the 2nd one as we see here @ 23:54 UTC July 4th
http://stereo-ssc.nascom.nasa.gov/browse/2012/07/04/ahead/cor2/1024/20120704_235400_d4c2A.jpg
Then we have the CME associated with the early July 7th X flare
http://stereo-ssc.nascom.nasa.gov/browse/2012/07/07/ahead/cor2/1024/20120707_022424_d7c2A.jpg
We will see at least a glancing blow from this CME around late July 8th, into July 9th
we have the "Expected Events" list updated on the solar blog (on the right hand side)
http://mysolaralerts.blogspot.com/

Also lets note that there was a lot of CMEs between July 4th and today, July 7th, that could have been caught up at least partially in a magnetic connection between earth and the sun. thus we could see some mass from these CMEs being caught up with the earth directed CME's and giving a combined hit. i would say we can expect at lease a Kp5 storm starting later tonight, that has the potential of reaching as high as a Kp7 at times, with the geomagnetic conditions being unsettled to Storm conditions over the period of the next 60hrs
With the ionospheric conditions being what they have been from the rash of M flares we have had over a 7 day period (33 M flares and 1 X flare as of the time of this post) combined with the heat wave we have had in North America this past week, i would caution as to the possibility of strong, strange storms for the period that the CMEs are expected to hit/arrive.

Again, this is my unofficial view. I make this blog post only as a informational post of my view with the limited data i have been able to review due to time limitations.

We currently have a S1 solar radiation storm in effect that was brought upon by the X1.1 Solar flare and associated CME that occurred earlier today. A greater than 10 MeV Proton event
associated with yesterdays X-class event began at 04:00UTC and peaked at 25 pfu. The proton levels are now subsiding but the S1 storm remains in effect as of 22:19 UTC July 7, 2012.



Global D Region Map as seen on July 8, 2012 @ 04:25

Conditions in the D-Region of the Ionosphere have a dramatic effect on High Frequency (HF) communications and Low Frequency (LF) navigation systems like Loran. The global D-Region Absorption Product depicts the D-region at high latitudes where it is driven by particles as well as low latitudes, where photons cause the prompt changes. This product merges all latitudes using appropriate displays, and is useful to customers such as commercial aviation and maritime users.

X1.1 Solar Flare - July 6, 2012

A X1.1 solar flare has occurred peaking at 23:08 UTC Friday July 6, 2012. Today's X flare comes from large sunspot region 1515.

SUMMARY: X-ray Event exceeded X1

Begin Time: 2012 Jul 06 2301 UTC

Maximum Time: 2012 Jul 06 2308 UTC

End Time: 2012 Jul 06 2314 UTC

X-ray Class: X1.1

Location: S18W50

NOAA Scale: R3 - Strong

Potential Impacts: Area of impact consists of large portions of the sunlit side of Earth, strongest at the sub-solar point.

Radio - Wide area blackout of HF (high frequency) radio communication for about an hour.

----------------------------------------------------------------------
SUMMARY: 10cm Radio Burst
Begin Time: 2012 Jul 06 2304 UTC
Maximum Time: 2012 Jul 06 2306 UTC
End Time: 2012 Jul 06 2306 UTC
Duration: 2 minutes
Peak Flux: 520 sfu
Latest Penticton Noon Flux: 158 sfu
Description: A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.

UPDATE @ 02:44 UTC July 7, 2012

There has been some question about the discrepancy seen between the GOES 3day Xray flux and the 5min Xray flux. We have noticed that the calibration for the 3 day Xray flux is off by around a 1.0 margin and has been that way for about a week now. Any M flare that we have had this week that was around M1 range has been showing on the 3day GOES Xray flux as a high C flare. Note the M flares on here and count how many M flares you see for July 6th

http://www.swpc.noaa.gov/rt_plots/xray_5m.html

on the 3day it shows 5, but we have had 6

http://mysolaralerts.blogspot.com/p/solar-flare-updates.html

same thing for the 5th.

Any M that registered around a M1 range was shown on the 3 day Xray flux as a high C. Now this X1 occurred and it does the same and shows this X1.1 flare on the 3day as a high M. The 3 day Xray graph is around a 1.0 mark off. We have written to NOAA/SWPC about this issue.

UPDATE @ 01:08 UTC July 7, 2012

ALERT: Type IV Radio Emission

Begin Time: 2012 Jul 06 2322 UTC

Description: Type IV emissions occur in association with major eruptions on the sun and are typically associated with strong coronal mass ejections and solar radiation storms.

We now see there IS a CME associated with this X flare event. Earth is well connected with the region of 1515. This CME was not directly Earth directed as it was ejected to the south and west. but a glancing blow to Earth's magnetosphere is likely late on July 9th into the 10th

X-FLARE: Giant sunspot AR1515 unleashed a strong X1.1-class solar flare on July 6th at 2308 UT. Because Earth is well-connected to the blast site by solar magnetic fields, a fusillade of protons accelerated by the explosion might soon reach our planet.
