It was business as usual last week with the solar flux index in the 180s, numerous C-class flares and, at the time of writing, 13 M-class flares over the past seven days. The Kp index has been mostly settled for this part of the cycle, averaging two to three all week. But this doesn’t mean […]

The auroral event last week was probably the strongest we’ve had in this solar cycle. There were widespread visible aurora reports from the UK on Sunday, 26 February. The Kp index eventually hit seven at 0900UTC on February, the 27th, sparking widespread visible aurora alerts all over the UK for Tuesday evening as well. The […]

Last week was characterised by many low- and medium-level solar flares. At the time of writing, in the past seven days the Sun has emitted more than 60 C-class flares, six M-class flares and one X-class flare. The X-class flare coincided with the measurement of the solar flux index meaning an erroneous reading of 343 […]

Last week was interesting as we had an X-class solar flare, and a significant geomagnetic disturbance, as well as good HF conditions at times. An impulsive X1.1 solar flare was observed around active region 3217 in the southeast quadrant of the Sun at 1548UTC on the 11 February. The flare did not appear eruptive, so […]

The solar flux index rose again this week with the arrival of more sunspots. By Thursday, the SFI had reached 192, up from 135 the week before. However, there has been some flare activity with minor C-class and some M-class flares, mainly from active region 3213. None of these have erupted in an Earthward direction […]

Well, what a difference a few weeks make. On the 15 January, the solar flux index was at 234 and the Sun was peppered with spots. This week, on Thursday, the SFI was at 134 and the solar surface looked like it was at sunspot minimum again. The Sun has also been mainly geomagnetically quiet, […]
