Type V solar radio emission in the midst of Type III bursts Recorded May 27, 2013 0031- 0033 UT. WIRED : Script ( Stardate style ) This super hot Type V solar radio burst event was generated by a small flare in the north central hemisphere of the Sun. See whitest spot in image below imaged in the hydrogen-alpha wavelength at 656.28 nm. The Type V radio component is the hotter ( brightest vertical ) burst at 00:31:12 in the spectrograph above. I believe you can also hear it begin to differentiate from the Type III bursting at about 32 seconds and peaking at about 40 seconds into the sound recording. Sound recording was made at 28 MHz and 21.1 MHz. Sound recording here: http://www.heliotown.com/Sr_May272013_0031ut2821TypeV_Ashcraft.mp3 Definition: "Type V solar radio bursts are defined as continuum emission following a Type III burst, x-mode polarized (opposite sense to the associated Type III). The cause is slower Type III-like electrons in widely diverging magnetic fields, with both forward and counterstreaming Langmuir Waves, perhaps generated by the previous passage of Type III electrons." Quote from http://web.njit.edu/~gary/728/Lecture11.html Sound recording was made at 28 MHz and 21.1 MHz on two separate Sangean ATS-803a radios attached to a three element tri-band yagi. Spectrograph instrument is a RF Associates FSX-4 running Jim Sky Spectrograph software. Thomas Ashcraft : Heliotown Observatory : More various observations Mail
