“It’s a Crazy, Unexplainable #Signal From #Space”:
Repeating #RadioBurst Every 2 Hours Baffles #Scientists and Reveals New #StarSystem

Bueno, en el Sol acaba de ocurrir una erupción solar clase X8.7 hace apenas un rato, siguiendo otras dos flares clase X1.7 y X1.2, la alerta por correo de esta última no ha llegado aún. Estos eventos fueron detectados por el radiotelescopio e-callisto del OALM y han ocasionado un type II y type III radio burst que son básicamente, señales de radio intensas, generadas por la aceleración por onda de choque de los electrones en la corona solar, que muchas veces acompañan las eyecciones de masa coronal o CMEs . El proyecto e-Callisto es una red internacional de estaciones terrenas con radiotelescopios de bajo costo que observan la actividad solar las 24hs distribuidos por todas partes del mundo entre 45 y 870MHz y que buscan detectar estos bursts o explosiones en radio. Esto ayuda a caracterizar la la actividad solar y en casos de eyecciónes de masa coronal, ayudar a determinar la velocidad de las partículas que vienen hacia la Tierra.

En su momento yo hice una página para el radiotelescopio que luego que yo me fui, dejó de mantenerse, pero aún está accesible con certificado vencido, donde se puede ver la última imagen del radiotelescopio y fotos del mismo --> https://radio.oalm.gub.uy

#Hubble Shows That a Fast #RadioBurst Came From a Giant Group of #Galaxies

Solar activity reached high levels when Region 3536 (N06E69,
Eai/beta-delta) produced an X5.0/3b flare (R3-Strong) at 31/2155 UTC, with complex radio burst signatures reported across discrete frequencies
by the USAF/RSTN observatories.

This flare also produced a 10 cm radio Burst of 3,100 sfu at 31/2143 UTC and a Type IV radio sweep at 31/2142 UTC.

In addition to the X-flare, newly numbered Region 3536 produced an M1.0 flare (R1-Minor) at 31/1912 UTC and an additional M2.3/1n flare
(R1-Minor) at 01/0854 UTC.
Minor growth was observed in the region in the past 24 hours.

A coronal mass ejection was observed in SOHO/LASCO C2 imagery beginning at 31/2200 UTC and was associated with the X-flare (R3) event from Region 3536.

The partial-halo signature is currently being analyzed and
modeled to determine the trajectory and timing of any Earth-directed
component.

.Forecast...

Solar activity is likely to reach moderate levels (R1-R1/Minor-Moderate), with a chance for X-class flares (R3-Strong),
over the next three days due primarily to the flare potential from
Region 3536
