Happy New Year! We should expect, though, that the number of days with alerts like this will peter out as we get closer to the trough of solar minimum. There are no sunspots at this time--so far that makes 103 sunspotless days for 2017.

This past Tuesday a C1-class solar flare sent material and energy almost directly toward Earth. This scant rate of activity will almost certainly remain for the next couple of years.

A co-rotating interaction region, in part, has led to these alerts from the SWPC. Contrary to the announcements on some media and on some internet sites, this is not going to be a "big" or "huge" solar storm. Those statements frustrate me immensely. G1 is the lowest of the alerts on the five-step scale!

The descent into the trough continues. The current prediction is for the sunspot number to remain under 20.0 for the entirety of 2019...

There was G2-level activity earlier today. Many of these instances coincide with optical activity on the Sun (spots and plage). This may be good news for visitors to tomorrow's International Astronomy Day event. Solar viewing is planned for 3pm to 5pm.

G1 conditions were observed at 12:59pm CDT, hence today's alert. A negative polarity coronal hole high speed stream is prompting the alerts for tomorrow and Monday.

The first two days of hurricane season arrive with G1 alerts! We should consider NOAA to now issue these fewer and farther between; the "bottom" of this solar cycle seems to have come sooner than predicted.

Tuesday 24 July: G1

According to Tony Phillips, there have been ~118 days so far without sunspots! AR2716 didn't stay long. Since it's been nine years since the Sun has been this spotless, it's a sure thing that we're experiencing solar minimum.
