Update (2:28 pm EST): "The shock passed NASA's Advance Composition Explorer spacecraft at approximately 1:30 p.m. EDT today, July 14," the Space Weather Prediction Center said. "Now watch for the CME and then, the imminent disturbance to the geomagnetic field. SWPC expects G1 (minor) and possibly G2 (moderate) geomagnetic storm levels over the next 36 hours."

Scientists continued waiting for a massive burst of solar wind and magnetic fields to impact the Earth on Saturday afternoon.

Scientists expected the Coronal Mass Ejection (CME) to arrive Saturday morning but as of 1:06 p.m. EST (7:06 UTC) they continued to wait for its impact on the Earth's magnetic field, according to the Space Weather Prediction Center.

The center however, said there were indicators that the storm was on its way.

"Look for that [impact] in the next few hours," the Center said on its latest report.

"Otherwise, similar to yesterday, Region 1520 has had the occasional Radio Blackout (flare), and the Solar Radiation Storm sits barely at the S1(minor) level; that may increase slightly with the passage of the CME," it said on the latest report.

As of 2 p.m. EST the Space Weather Prediction Center detected a solar radiation storm of a S1 magnitude, the lowest in a scale 1-5 which can cause minor impact on HF radio in the polar regions.

The large solar flare and coronal mass ejection (CME) was caused from a solar storm eruption on Thursday.

Scientists compared it to a mountain of solar energy.

"Imagine something with the mass of a mountain being ejected at a speed of a million miles an hour," John Raymond, a physicist at the Harvard-Smithsonian Center for Astrophysics told ABC News.

But scientists also have said it was possible that the CME will miss the Earth,

However, if the event occurs, it's most notable effect on earth would be auroras, Raymond told the network. Auroras are commonly visible at high latitudes such as in Northern Michigan and Maine.
