G7IZU Radio Reflection Detection

Binge-watching of "Breaking Bad" can continue without interruption.

Several active regions are in view on the solar disc, but none show signs of significant activity.

Geomagnetic conditions at Earth are quiet. Minor substorms have affected high-latitudes.

No significant activity is predicted.

Breaking the silence: An M2.3 flare erupted from a new active region on the east limb, peaking at ~15h50 UT 25 Feb.

The sun is spotless for the first time since 2022! This is definitely a sign that we're on the long slide back down to solar minimum. The official synoptic map is currently showing no active regions on the visible disc!

There have been minor substorms and minor geomagnetic activity with aurora visible at high-latitudes, thanks to the fast solar wind from a coronal hole.

Space Weather

Space weather is currently fairly quiet. The X-ray flux has not exceeded C3 level in over six days. There has been some CME activity but none Earth-directed.

To understand how they form, you have to picture the Sun as a rotating lawn sprinkler, spraying out streams of plasma at different speeds.

A new coronal hole will be facing Earth an a day or two. This CH will push out a fast solar wind which is negatively polarised, so it should be good for aurora in 4-6 days.

A moderate G2 geomagnetic storm is in progress. The fast solar wind from a large coronal hole is now influencing the Earth's magnetic field.

Aurora is visible at high-latitudes.

Aurora Alert: Aurora may soon be visible to mid-latitudes as a effects of a coronal hole and glancing CME take hold. Aurora is currently visible at high-latitudes. A moderate substorm is in progress at Kiruna.

A trans-quatorial coronal hole is transiting center-disc. The fast solar wind from this and a possible glancing blow from a CME (coronal mass ejection) may cause disturbed geomagnetic conditions from today 14 Feb until Monday 16 Feb.

Solar and geomagnetic conditions are currently mostly quiet.

The next few days will be mostly quiet with substorms possible, but returning active regions may produce flare activity above M-level as they come back into view. Radio noise will be moderate this week.

Forecast: A small solar storm was launched by AR4371 which could raise geomagnetic activity on 12/13 Feb. Aurora may be visible at high latitudes.

Solar Flare Alert: There were three flares from AR4366 above M-level in the last few hours.

M1.7 @11h19 UT 08 Feb
M1.7 @11h47 UT 08 Feb
M2.7 @13h47 UT 08 Feb

The M2.7 flare was eruptive, producing a 10.7cm radio emission. There appears to be no earthward CME.

CME Arrival: An interplanetary shock has been detected at ACE/DISCOVR (L1) indicating the arrival of the CME which originated from the X8.1 flare late on 01 Feb. The IMF strength is 22nT.

A G1 geomagnetic storm warning is in effect for 05-07 Feb (UT).

Solar Flare Alert: An X1.5 flare peaked at ~14h05UT 02 Feb,. Another large flare is approaching X-level as I type this at 15h UT (currently at M7.2).

#spaceweather

I checked the NOAA definition for a solar flare, and actually they do count *every* peak (based on certain parameters), so apologies for my error.

#spaceweather
#g7izu

Solar Flares: There have been around 19 flares exceeding M level since 10h UT 02 Feb (yesterday). The largest was an M7.2 peaking at 07h UT 02 Feb.

AR4366 continues to be very active. It's looking a little less potent now but the potential for large flares continues.

CME update: NOAA (US) and Euphoria (European) solar wind models suggest the CME imact could be a little later than the early NASA model.

Yes I agree, I can't see any actual event coverage in the radio schedules. It can only be a budgetary thing as there's really very little money left in the pot to do actual broadcasting any more. It's a fact across all our outputs. It's very sad.
