X9 Flare


 

¿ªÔÆÌåÓý

A pronounced? effect from the X9 flare yesterday seen my magnetometer:

?I saw no significant effect on muon or total counts.
(Red - DHO 23.4 kHz, blue - total count, orange - muon count )



An interesting small dip in sferics level, co-incident with the flare:

I too saw the magnetic effect of this flare using a UKRAA MAgnetometer in Kent. I have been told that the sharp dip and recovery seen in the Inclination signal is called a magnetic crotchet due to its resenblance to the musical note. I have not seen an extended SID like dip as seen in the declination signal before.
Today the magnetometer is starting to move away from a quiet day profile. Aurora tonight?d recovery
