New Coronal Hole Geoeffective Sept 21
Not much activity for tonight, and some clouds in many regions of Maine, but, starting on September 21, this particular coronal hole may give us some fireworks. Not as good as the Butterly Blaster this past weekend, but we may get to an Orange Alert level. Space Weather Class We had our first inaugural Space […]
Coronal hole facing Earth
We could see enhanced solar wind plus or minus 3 days from this bad boy, but, so far, no major CMEs detected. This coronal hole is a bunch bigger than it was on the last rotation, and was responsible for many alerts the last time around, too. We might see some activity by Friday, and […]

A Good Moment to Compare/Contrast kP with Observed Conditions
The NOAA Three-Day Forecast, in black with white letters, reflects kP predictions based on averaged data from 13 magnetometers around the world. However, these magnetometers only update every three hours. Given that, it’s easy to see why real time data coming off ACE/EPAM can sometimes conflict with kP forecasts. Here, we see that the kP […]
UTC 00:00, September 9, 2025
Greetings and welcome to the almost-new universal day. I’m writing a little bit earlier because it’s getting darker earlier. It’s clear up in the county, according to NOAA anyhow, and a look at the Katahdin webcam reveals our patron mountain in all her glory and majesty beneath a blue raspberry sky. There is a rather […]
Coronal Hole Active 4-8 September
Just when we thought the fun couldn’t get any funner! I will say, the moon is now going to be a definite deal breaker, at 89% full tonight, and moving on from there. However, I’m waiting for folks to mention that there’s a full lunar eclipse on the 7th. If you look at the sidebar […]
Victory Lap!
After veering off last night around 1 am, the IMF from last night is large and in charge this evening, hence, the big purple block of data far to the right in the above graph. We should have clear skies tonight, and, if conditions hold, hopefully those who were unable to see anything in the […]
Impact, Early.
Well, so much for everyone trying to figure out UT and setting alarms. Looks like the show has started. Just before 5 pm Maine time, I was either going to go clear out part of my barn or look at data. And then do the barn. I’m still here looking at data. Yes, this happens. […]
A Storm a-Brewing
We had a pretty decent full halo CME yesterday, which is going to lead to possibilities of good sightings on camera here in Maine. This is what a written NOAA forecast looks like, which can be found below the UTC time and kP index chart. It generally leads to confusion, because people equate the dates […]
