I have several questions. I have noticed that lately Seti@home has been processing observations from 2007. I know right before hurricane maria struck we were working on thinks from 2017. Why is it we had been working on more modern stuff when this 2007 data needed to be processed? Why has this data that is like 10 years old just now been processed? or was it processed before and we are just going back over it again running through more modern methods looking for signals? Pertty much can someone explain all the details about this 10 year old data. and why this data is just now coming to light 10 years past its observation date.

We're redoing them because they havn't been done with the latest app versions yet. ;-)

From a "Nature" article I have learned that the hygienic and medical situation at Puerto Rico is very poor, due to lack of electricity to run refrigerators, freezers and all kind of electromedical equipment. Most biology research projects at the University had to be abandoned.

Since SETI@home piggybacks on the signal when others are using it the projects doesn't get data all year long.
You can check the Telescope Schedule for The Arecibo Observatory to see what dates it is scheduled for activity.
I believe the project only records data when the observations are compatible.
I would imagine that while Arecibo Observatory is looking for near Earth objects that no SETI@home data can be generated.

Is now a very good time for s@h data collection at Arecibo whilst the telescope is left in a statically pointed sweep-as-the-earth-rotates?

Or is there no power and support to run the s@h recorder?...

Yes it is, but read a bit further.

That decision comes with a big sigh of relief, says observatory director Francisco Córdova, even though it’s not yet clear who will manage the observatory and where the additional funding will come from. “That adds a level of complexity and stress going forward,” he says. “But today we’re better off than we were yesterday.”

Though the observatory sustained damage from the hurricane and is still without power, its deep well provided water for local communities, and its helipad served as a base for supply distribution. Observatory staffers helped clear roads and allowed residents to communicate with others via short-wave radio.

It also provided the first indirect evidence for gravitational waves, spotted the first planets orbiting a star other than the sun, and—43 years ago to the day—sent the first targeted message to the stars as part of the Search for Extraterrestrial Intelligence, or SETI (a project of former observatory director Frank Drake, who happens to be my dad)
It looks safe, but we need confirmation of the money to be absolutely sure.

Just a quick question: Is there a way to donate to Arecibo? Fundraising or so?

It's been a while, so I thought I'd raise this thread up to the top again. Anyone heard anything new about Arecibo since the last posts were updated above?

Arecibo used its radar capabilities using diesel generators to watch asteroid Phaeton3200, as reported in Science (non SETI) section.

Informative backgrounder video on this asteroid (and some tidbits about the situation of the Arecibo observatory and... and its cats' colony).

For the person who asked how s/he could directly help the observatory: not sure. But there are other ways:

Message 1910834 - Posted: 5 Jan 2018, 16:39:45 UTC - in response to Message 1910734.  

Thanks for the info, a blurb at the end of the article caught my eye:

Even beyond the hurricane recovery process, the science being done by the Arecibo telescope would be facing a period of some upheaval after the National Science Foundation, which owns and operates the facility, decided to dramatically decrease its funding of the site.

After considering a few potential paths, the NSF in November decided to focus on building partnerships with other groups to fund the site's work, and an announcement about who will be managing the facility beginning next spring is due imminently. "This has been a long wait," Mendez said, but November's decision not to shutter the facility was welcomed by the Arecibo community.

The article pretty much glossed over the repair part of it, which I was hoping might have been fleshed out a little, but maybe it's still too soon to know the intimate details of that one.

I've read that Elon Musk plans to install a huge Lithium Ion battery in Puerto Rico like the one he has installed in Southern Australia, powered by photovoltaic cells.

According to "Nature" magazine Arecibo has found both a new funding source which will take the place of NSF and 16 Fast Radio Bursts in the 121102 source in the Auriga constellation, which has allowed to measure the linear polarization of the radiation emitted, whose angle varies from burst to burst. This makes to think of a source, possibly a neutron star, in a high magnetic field which may come from a black hole. The source should then consist of a binary system made up from a neutron star and a black hole. Kudos to Arecibo!

La Repubblica paper shows the front cover of "Nature" with images of Arecibo and Daniele Michilli, Amsterdam University, spokesman of this research which used also the Green Bank Telescope.

Thanks for the heads up! Was there any mention of repairing it to the condition it was before the storm, or even doing some (I can only presume from everything I've heard about it's relative neglect over recent years) much needed repairs or heavens forbid _upgrades_ to it since they are already there working on it? My guess is that would be a bridge too far, but hopefully they would at least get it repaired back to pre-storm condition.

The article did not speak about the conditions on Arecibo, it only gave its scientific results. I've noticed that among its authors are also Chinese scientists, besides American and European scientists. The results also are narrated in a Scientific American article, which I could read in the Italian version in "Le Scienze" online magazine. I've read in a New York Times video article that the main problem now in Puerto Rico is the number of attempted suicides of people living without electricity, and a telephone help center is working day and night.

If I go to "Le Scienze" article on the FRB and click on the "Nature" article link I can read the full Letter article through Springer Nature Sharedit without paying any fee. The Letter is very long and detailed. I know that Le Scienze has an agreement with "Nature".
