Sun shoots out massive solar flare early Friday, only a few days after it fired off a solar storm at earth.

The massive solar flare that shoots out registered as an X1.7-class solar event on the space weather scale, peaked at 4:01 a.m. EDT (0801 GMT), according to an alert by the NOAA-run Space Weather Prediction Center. An X storm is considered the strongest of the three categories - C, M and X.

The X-class sun eruptions can interfere with satellite-based communications and navigation systems, endanger astronauts in orbit. Even though the sun shoots out these massive solar flares over the span of a few days, it should not be major geomagnetic storms in Earth's magnetic field, according to SWPC.

"Increased numbers of flares are quite common at the moment, since the sun is near solar maximum," NASA officials wrote Thursday while discussing the Oct. 23 solar flare. "Humans have tracked solar cycles continuously since they were discovered in 1843, and it is normal for there to be many flares a day during the sun's peak activity."

There could be geomagnetic storms that can disrupt radio communications, GPS signals and power grids. Earth's auroras can ramp up as well, which is also known as the northern and southern lights.

The fallout from those solar storms are expected to spark a G1 geomagnetic storm on Earth today, SWPC officials said.

"Earth's magnetic field is about to receive a glancing blow from three CMEs observed leaving the sun between Oct. 20th and 22nd," astronomer Tony Phillips wrote Thursday on Spaceweather.com, a website that tracks skywatching and space weather events.

"Forecast models suggest that the three clouds merged en route to Earth, and their combined impact could trigger a mild polar geomagnetic storm on Oct. 24-25," Phillips added. "High-latitude sky watchers should be alert for auroras."
