Yes Members what you heard is true ?
Its true that Two Coronal Mass Ejection (CME) from sun is traveling towards earth. It is estimated to hit earth's magnetic feild on 3/4th August.
Latest Update :
The first of possibly two incoming CMEs hit Earth's magnetic field at approximately 1730 UT (11 p.m. Indian Standard Time).

Members, I have lot to talk on this but need time to write. Here are some exepreience and faq for you.
My experiences - Journey of Sunspot 1092 so far :
I was personally fascinated by this sunspot 1092 when it first appeared on eastern limb of sun while 1089 was exiting on other part of Sun's limb from our view
then 3days ago there was another news that this sunspot 1092 is as big as our earth. And was visible to naked eye during early morning sun rise.
Then on 1st August there was alert on auroras observers due to this CME which was expected to come towards earth.
And on 3rd August with NASA release entire world, t.v.'s were beaming breaking news on Two CME'S reaching earth in 24-48 hours.
What Exactly happened ?
On August 1, 2010 around 0855 UT, Earth orbiting satellites detected a C3-class solar flare. The origin of the blast was sunspot 1092. At about the same time, an enormous magnetic filament stretching across the sun's northern hemisphere erupted. NASA's Solar Dynamics Observatory recorded the action.
On August 1st around 0855 UT, Earth orbiting satellites detected a C3-class solar flare. The origin of the blast was Earth-facing sunspot 1092. C-class solar flares are small (when compared to X and M-class flares) and usually have few noticeable consequences here on Earth besides aurorae. This one has spawned a coronal mass ejection heading in Earth's direction.
What exactly is a Coronal Mass Ejection (CME)?
Coronal mass ejections (or CMEs) are large clouds of charged particles that are ejected from the Sun over the course of several hours and can carry up to ten billion tons (1016 grams) of plasma. They expand away from the Sun at speeds as high as a million miles an hour. A CME can make the 93-million-mile journey to Earth in just three to four days.
What exactly happens when CME's reaches Earth ?
When a coronal mass ejection reaches Earth, it interacts with our planet’s magnetic field, potentially creating a geomagnetic storm. Solar particles stream down the field lines toward Earth’s poles and collide with atoms of nitrogen and oxygen in the atmosphere, resulting in spectacular auroral displays. On the evening of August 3rd/4th, skywatchers in the northern U.S. and other countries can look toward the north for the rippling dancing “curtains” of green and red light.
What exactly is happening on Sun ?
The Sun goes through a regular activity cycle about 11 years long. The last solar maximum occurred in 2001 and its recent extreme solar minimum was particularly weak and long lasting. These kinds of eruptions are one of the first signs that the Sun is waking up and heading toward another solar maximum expected in the 2013 time frame.
