 On April 4, 2026, a major X-class solar flare of M1.0 magnitude was observed at about 22:54 UT in active region NOAA 14409. The flare was recorded by GONG/Big Bear station using its Hydrogen H-alpha instrument. GONG/BB restarted its observations on the day of flare after been down for a preventive maintenance. Image shows the location of flaring region before (22:39 UT) and during the flare (23:02 UT, marked by thick black arrow). The active region continues exhibiting a complex magnetic configuration and new flux emergence, and thus, may produce additional flares. The observations can be access via GONG website.
