August, 2025 - Maine Aurora Borealis Watch

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 […]

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 […]
