Shadow profile of slow-rotating asteroid (144) Vibilia measured by 6 stations in Poland and Germany on 2025 April 4. One additional observer reported a negative observation from the northern edge of the shadow.

The team of SODIS has calculated a preliminary profile of the asteroid of 134 x 134 km.
The dashed line shows the predicted centre line of the shadow. Another very accurate prediction.
The International Occultation Timing Association (IOTA) in the US was present at the Northeast Astronomy Forum (NEAF). Have look at IOTA's booth with the presented equipment and posters about stellar occultation observations.
Das scheint ein spannendes Projekt zu sein bei dem jeder mitmachen kann.

Es sind auf dem Weg wohl schon neue Bakterien gefunden worden, die auch gegen sog "Krankenhauskeime" wirksam sein könnten.

The team of the Stellar Occultation Data Input System (SODIS) of IOTA/ES has calculated a preliminary profile of the asteroid of 61 x 47 km from these measurements.
The dashed line shows the predicted centre line of the shadow. Very accurate prediction.

This week’s CMOR photo is from Meade County, #SouthDakota.
“These are a few of our stock dams that are nearly dry and ponds that are completely dry that we rely on for our cattle to water from. Also, our pasture in Meade County has no forage left. Having to feed hay much earlier and later in the year and more often than we ever have. Cattle are struggling to stay in good condition.”

This survey needs YOU! There are 1,440 responses so far, 60% of the goal. It is open to everyone, everywhere, and there are three easy radio button questions.

It's time to start digging in to my mask project!
I need good, solid resources to back up a presentation I'll be giving to the local public. What are the most reliable and ethical doctors, journalists, advocates, research, statistics, or sites that you've seen?
I'll be talking about air quality, advocating environmental justice through citizen science and mutual aid, and my focus is going to be ventilation and masking.
The program is organized by a local group of folks that started putting up air sensors all over town because of toxic chemical leaks from nearby refineries. They got a grant through a university, and they may be able to help me out in getting an air quality sensor so I can test the CO2 in local buildings. I'd also like to be able to pass out some mask samples. I've been trying to find info on other things like sip valves, elastomeric respirator exhaust valve filter adapters, good sites to buy masks and so on.
Since these issues got politicized and the CDC and WHO are increasingly corrupt/hamstrung, finding good info is a fuckin MESS. I could really use some help!
What's been very interesting to me is, the folks who promote masking are usually ALSO right on other issues. Masks are required at the local anarchist book fairs, for example, which to me says a LOT. The people I follow here on Mastodon who are solidly against genocide, fascism, capitalism, and lesser evilism are the SAME people who are solidly for issues like universal healthcare, right to repair, accessibility, direct action, labor organizing, etc etc-- you have a moral consistency that inspires my respect and hope, and I want to learn more from you!
Next post below will be where I list the sources I've collected, updating as I go.

On this day fourteen years ago, on 6 April 2011, the second radio pulsar discovered with @einsteinathome was published.
Our distributed computing project had started almost exactly two years earlier to analyze data from the Arecibo radio telescope with the help of tens of thousands of volunteers.
This second discovery was special: the pulsar orbits the common center of mass with a white dwarf in just 9.4 hours and it belongs to a rare “species”.
At the time, it was assumed that this pulsar could be used to observe relativistic effects. This was finally achieved in 2022 after many more observations: https://www.aanda.org/articles/aa/full_html/2022/12/aa44699-22/aa44699-22.html
A shadow profile of asteroid (3560) Chenqian was measured during a stellar occultation for the first time by 3 observers in Germany and Poland on 2025 April 02.
The team of the Stellar Occultation Data Input System (SODIS) of IOTA/ES has calculated a preliminary profile of the asteroid of 31 x 22 km from these measurements.

Heute vor 14 Jahren, am 6. April 2011, wurde der zweite mit @einsteinathome entdeckte Radiopulsar veröffentlicht.
Unser verteiltes Rechenprojekt hatte ziemlich genau zwei Jahre zuvor begonnen, Daten des Arecibo-Radioteleskops mit der Hilfe von zehntausenden Freiwilligen zu durchsuchen.
Diese zweite Entdeckung war besonders: Der Pulsar umrundet mit einem Weißen Zwerg den gemeinsamen Schwerpunkt in nur 9,4 Stunden und er gehört zu einer seltenen „Spezies“.
Damals ging man davon aus, dass man mit diesem Pulsar Effekte der Relativitätstheorie beobachten könnte, was nach vielen weiteren Beobachtungen schließlich 2022 gelang: https://www.aanda.org/articles/aa/full_html/2022/12/aa44699-22/aa44699-22.html

The latest issue of the Journal of Double Star Observations (JDSO) Vol. 21 No. 2 presents several papers about discoveries of double stars by measuring stellar occultations by asteroids.
Many thanks to the observers and the authors of the papers.
