Solar Eruptions Spark Excitement for Space Weather Enthusiasts

Get ready, space lovers! Astronomers have been buzzing about two recent filament eruptions from the Sun that could lead to a G2 – Moderate geomagnetic storm expected to hit Earth on April 16. The first eruption, stretching a staggering 20 degrees, erupted around 21:30 UTC on April 12, while a second, 12-degree eruption followed suit on April 13. Both events sent shockwaves through space, leaving visible plasma trails observed by coronagraph imaging.

What to Expect from the Upcoming Storm

The initial analysis of the second coronal mass ejection (CME) suggests it’s headed straight for Earth, with an expected arrival around midday on April 16. Keep your radar tuned, as this storm could spark minor power grid fluctuations and disrupt satellite operations. And for those located in higher latitudes, be on the lookout for a magical display of the northern lights!

Solar Activity on the Rise!

As we approach this cosmic event, solar activity remains on an upward trajectory, with a slight chance for isolated X-flares on April 14 and 15, thanks to the active Region 4055. However, the activity is expected to dip to lower levels by April 16 as this region moves out of view.

Keeping Track of Solar Winds and Radiation Levels

The solar wind has been quite spirited, with particle fluxes fluctuating. The greater than 2 MeV electron flux hit high levels recently and is expected to hover at moderate to high levels up through April 15. Watch out for a potential S1 – Minor solar radiation storm around the same time.

What’s Happening in the Solar Wind?

Influences from a high-speed stream (CH HSS) of negative polarity have kept solar wind parameters elevated. Over the past 24 hours, solar wind speeds have decreased from about 465 km/s to 435 km/s. The Bz component has been bobbing between -6 and +4 nT, making this a complex yet intriguing time for scientists.

Get Ready for Aurora Bores!

By mid to late day on April 16, significant enhancements in geomagnetic activity are anticipated following the arrival of the CME. The geomagnetic field has been at quiet to active levels recently, but as we near the date, conditions are expected to ramp up.

Mark Your Calendars!

If you’re keen on witnessing these natural wonders, keep your eyes peeled on April 16 when G1 – Minor to G2 – Moderate storm levels are likely. It's the perfect chance for some awe-inspiring auroras!
