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 […]

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 […]

UTC 22:55, almost tomorrow. In Space.

Well, at about 3 pm we had a good hit. bZ -5 nT. Aurora is absolutely viewable on camera at that level. But, it’s now not 3 pm. In fact, it can be none more 3 pm. I’m usually functioning in about three different time modalities, so- maybe it’s a moment to discuss Universal Time, […]

Welcome to the new universal day! A minor substorm is underway, with readings fluctuating just on either side of the line between what is negative and what is positive- which, frustratingly, NOAA often denotes as -0. They don’t always. But it does happen, and if you read ACE data, coming through on the old DISCOVR […]

Most places are still in clouds. A minor substorm is underway, very weak activity possible over the next hour. Strongest portion of the storm was about a half hour ago. I was availing myself of a nap, it being cloudy.  Current reading:

Welcome to the New Universal Day, 00:08 UTC. Also “Z.” Or “Zulu” time. I don’t know if the military still calls it Zulu though. But, if you get the NOAA bulletin updates, they are in “Z” time. Which is exactly the same as UTC. There is a small substorm brewing, but it will probably not […]

Welcome to the New Universal Day! Star Date 00:13 UTC, August 24, 2025. A substorm is brewing, but in the hovering around the zero demarcation variety. Low Energy Protons ramped up about an hour ago, but have since fallen off. Possible sightings on camera after it’s completely dark, but it will be weak. We can’t […]

But Wait- There’s More!

As of Maine Time 7:38 PM: Solar Wind Speed: 496 km/sec Solar Wind Magnetic Fields: Bt 4 nT, Bz -1 nT WELL, just when I told you that I didn’t think there’d be any more activity from this period. Surprise. NOAA didn’t forecast it, either. But, I’m seeing negative solar wind trajectory. It’s not super strong but neither was last night, and plenty […]
