Just finished my reviews for this year's BOSC conference (@OpenBio) while waiting for our plane. It's always a joy to see abstracts covering so many dimensions of #openscience & #citizenscience!

I have an odd little side project (one of many ) that can probably be best described as a new type of environmental sensor.

That sort of thing doesn't really fit my usual range of #HCI conferences, though, except maybe if you frame it in the context of "citizen science" or "urban sensing"? Would anyone have an idea where to publish something like this? (Open access venues strongly preferred.)

Slow change is hard to notice. But frequency of occurrence is quite easy to see. Use that to talk about climate change with the “unconvinced”.

It is also a nice project for citizen science. Dig through local sources to find which years a local lake froze.

Next #SETILive: Unistellar + Citizen Science Q&A (Part 6)
TODAY, Thursday, Apr 17, 11:00 AM PDT

Join Dr. Franck Marchis and Dr. Lauren Sgro for a conversation on citizen science with the Unistellar network in partnership with the SETI Institute. We will give an update on T CrB, share our new Satellites mode, discuss an exoplanet candidate campaign to confirm a planet, and look ahead to an occultation of asteroid 319 Leona.

The European Citizen Science Association has created a Mastodon account (@ECSA), but they have haven't posted yet.

They just announced at the annual general membership meeting that they are planning on starting to post to Mastodon soon.

If you are interested in #CitizenScience and want to encourage them to post more here (and less on for-profit platforms like Bluesky), please follow them

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.

https://cloud.occultwatcher.net/event/1554-144-149652-648999-U050651

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.

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.

If you were born in the southern hemisphere or you were born in February, January or September then you are underrepresented and this survey *especially* wants to hear from you!

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.

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.
