  1. Was the compass far away from any electronic device and or magnets? These can influence the needle of the compass. If it was a digital compass, there is always interference of the device itself.
  2. It’s always the same at the end of a solar cycle, always a vast amount of scientist with different outcome on the prediction of the next cycle. The methods they use are always based on good research and data but still, the inner workings of the Sun are still so much unknown that it can’t be predicted in a perfect way. It’s good that there are multiple predictions to see what methods they used and how they think it will evolve. It can improve the predictions of others and improve them. With the sc24 predictions we started the cycle with two versions because they couldn’t agree and “the board” chose the stronger and a weaker cycle for sc24. It was untill after the long minimum that they abandoned the stronger cycle. Just to say that there is no good method for a prediction and you better wait and see what time brings...
  3. Nice to see a new SC25 region with some activity.
  4. We currently have one active Spanish translator who's done most of the work except the help section.
  5. Solar activity causes geomagnetic storms. It does not cause a reversal of magnetic poles of the Earth. The stronger solar wind of a strong coronal mass ejection pushes the magnetic field lines of the Earth inwards on the sunlit side. Please read our help section to learn more about solar storms and the effects they cause.
  6. What I meant with "latitude seems too high" is that new cycle spots mostly appear around 40° latitude, the latitudes you had in your pictures was higher and thus not very plausible that regions would start appear there. I found an other diagram with pretty recent data: Also a very good research study on the solar cycle: https://www.researchgate.net/publication/227138551_Long-Term_Solar_Cycle_Evolution_Review_of_Recent_Developments
  7. New spots are only defined if they are visible in white light or on the HMI instrument of SDO, not before. If the spot(s) still exist after 00:00 midnight a new region number is officially assigned.In the cases above, there was no visible spot in white light and/or HMI instrument. The butterfly diagram you posted is an older one than the one J. Janssens has and is a bit more detailed 😉
  8. The butterfly diagram gives the sunspot regions latitude in the y and time in the x axis. Where sc24 fade out more and more sc25 regions would take over. I didn’t find an updated chart 😕 (most recent is that of Jan Janssens of February 2019) The images with a brighter zone is not a zone where a region would appear, latitude seems too high too. Just some granules of the Sun, nothing fancy. I guess HMI didn’t give anything for that place either?
  9. I did look but it's still in my opionion mostly guesswork and time will tell who was right 😉 . As long as the scientist don't know the exact inner workings of the Sun, the predictions of solar minimum and maximum will be very variable. Before the previous minimum there where a lot of different oppinions of many scientists and it turned out that half wasn't right. Let's evaluate in 6 months where we are 😉
  10. We don't provide downloadable exports of our archived data, please use the data from the official organisations. Kp/Ap data can be retrieved from the Potsdam website where the finalized official Kp can be downloaded in a few formats.
  11. Both new regions are still from old cycle, if we where past minimum, we would see more SC25 regions appear and that's not the case yet. Still old SC24 regions emerge so it still looks that the minimum has yet to come.
  12. That's because the source is different. May 29th had no visible sunspot regions and no spots, as well as the day before and after. SWPC gave out a SN of 0 which still seems corect. No region was numbered as well so it must have been a shortlived one that was registered in some stations of the SILSO network that record the SN. SWPC has their own counting 😉
  13. It wasn't meant to be offensive. One of the questions was what the abbreviations where on the right side of the image, it was all explained on the magnetometer page and thus I thought you might have not seen the "details" button that reveals more information about those stations. That's why I mentioned that first. Second, I had a clear explanation below the first paragraph to give you more information on the things you asked about to digg in deeper then the information on the magnetometer page. If I was offensive, I would have stayed with one paragraph, but I did my best to give you more detail.
  14. I guess you didn't read the help information that is above the stack plot on the site and you should have clicked on 'details' under the plot on the site too so you would know what the abbreviations on the right are... also read in our help section more about how to read a magnetometer like Kiruna (is similar as this) and what they are used for. Every magnetometer does its measurements in nanoTesla, this stack plot contains the data of several magnetometer stations (abbreviated on the right). The station with the highest latitude is on top and the lowest latitude at the bottom. For each station you'll find on the left the reading in nanoTesla. The zeros are simply no data for that station. The gaps in the readings are just times where data was invalid and thus excluded from the set. As geomagnetic storms happen around the poles, the magnetometer will react quicker and heavier there, the more south we go, the less the magnetometer reacts to a disturbance. For example a viewer in Belgium, they could see the northern lights if the magnetometer of Sol starts to dive together with the above magnetometer stations. Here's an example of march 16th when photographic aurora was seen in Netherlands due to a substorm: It's a good tool for tracking substorms and for middle latitude watchers to know when to go out.
