An impulsive solar flare measuring X1.5 erupted from geoeffective Active Region 3764 at 02:37 UTC on July 29, 2024. The event started at 02:33 and ended at 02:43 UTC. As a result of recent solar activity, a G3 \u2013 Strong geomagnetic storm watch is in effect.<\/strong><\/p>\n

A Type II Radio Emission with an estimated velocity of 535 km\/s was detected, indicating a coronal mass ejection (CME) was associated with the flare event.<\/p>\n

In addition, this event was associated with a 10cm Radio Burst lasting 1 minute and with a peak flux of 300 sfu. This indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.<\/p>\n

We are still waiting for coronagraph imagery but judging by the location of Region 3764 in the center of the disk, an Earth-directed CME is likely.<\/p>\n

Radio frequencies were forecast to be most degraded over East Asia, Australia, and the Pacific Ocean.<\/p>\n

This event follows several days of increased solar activity with multiple Earth-directed CMEs, including cannibal CME.<\/p>\n

As a result, a G3 \u2013 Strong geomagnetic storm watch is in effect for July 30, according to the SWPC.<\/p>\n

Keep in mind this forecast still doesn\u2019t take into account today\u2019s CME, so we might be looking at prolonged geomagnetic storming in the days ahead.<\/p>\n

The same applies to this great analysis by space weather physicist Dr. Tamita Skov, published on July 28:<\/p>\n
