According to the National Oceanic and Atmospheric Association (NOAA), space weather forecasters have observed “at least seven coronal mass ejections [CMEs] from the sun, with impacts expected to arrive on Earth as early as midday Friday, May 10, and persist through Sunday, May 12.”

The prediction prompted a warning for pilots from the FAA.

“Geomagnetic storms can disrupt navigational aids and high frequency radio transmissions used in aviation. The FAA advises airlines and pilots to plan ahead to mitigate possible disruptions,” the agency said in a statement.

NOAA issued a Severe (G4) Geomagnetic Storm Watch and states these watches will be updated through the weekend.

First G4 (Severe) geomagnetic since 2005 has been issued.

The aurora tonight (5/10) /tomorrow morning (5/11) may become visible over much of the northern half of the country, & possibly as far south as Alabama to northern California. https://t.co/upPlNYuNev@NWSSWPC @NWS pic.twitter.com/JTHmXtRKOc

According to NOAA, coronal mass ejections (CMEs) are explosions of plasma and magnetic fields from the sun’s corona. These storms can disrupt satellites and infrastructure in near-Earth orbit, “potentially disrupting communications, the electric power grid, navigation, [and] radio and satellite operations.”

The agency refers to the situation as “an unusual and potentially historic event” and warns satellite navigation (GPS) may be degraded or inoperable for hours, and high frequency radio propagation could be sporadic or blacked out.

These storms are also visible from the Earth as displays of aurora and  may result in displays being seen as far south as Alabama.

This is a developing story.

Satcom Direct (SD) announced its plan to acquire satcom equipment maker TrueNorth Avionics at the National Business Aviation Association’s convention in Orlando, Florida, this week.

The acquisition of TrueNorth, which develops and manufactures satellite communications products for business jets and avionics OEMs, will broaden SD’s avionics portfolio, says SD CEO Jim Jensen.

“The ingenuity behind the Satcom Direct Router (SDR) and our SD Pro flight operations platform combined with TrueNorth’s highly advanced avionics will give aircraft operators an unrivaled ability to manage their aircraft communications systems, while giving passengers a user experience which exceeds their expectations,” said Jensen.

The transaction is expected to close in the fourth quarter of this year, allowing TrueNorth to continue developing avionics technology as a business unit of SD.
