    NOAA maintains a list of 'Solar Proton Events'. My boss maintains a copy of the data, which has an extra footnote:
    The >10 MeV proton event began on January 16 at 0210 UTC following the X2.6 flare late on the 15th. The peak flux following this flare was 365 pfu at 16/1840 UTC. The >10 MeV protons decayed to 117 pfu by midday on January 17 when a stronger injection of protons occurred following the X3.8 flare and CME. This new infusion began at 17/1240 UTC and peaked with 5040 pfu at 17/1750 UTC. The event decayed to about 19 pfu early on January 20 when yet another proton flare occurred. The X7 flare and CME that occurred on January 20 produced the hardest and most energetic proton event of Cycle 23. The >10 MeV protons peaked at 1860 pfu at 20/0810 UTC. The >100 MeV protons peaked at 652 pfu at 20/0710 UTC, which was the highest &gt100 MeV proton flux level observed since 1989 October (680 pfu). The >10 MeV proton event finally ended at 22/1755 UTC.
    So, the CME (believed to be) associated with it occured about 3 hrs before GOES got hit by it.

  3. SOHO, STEREO, SDO, etc. on NASA Notices New, Nasty Solar Storm Type · · Score: 4, Interesting

    The problem is, that although you can place satellites there, getting data from some of these places is a big problem, because you have to schedule antenna time through the deep space network.

    Currently, there's the ESA-NASA project SOHO, the Solar and Heliospheric Observatory, which sits near L1. You can't actually place it directly in the sun-earth line, because then you can't communicate with the satellite, because of too much noise from the sun.

    Currently in testing are the two observatories called STEREO, the Solar TErrestrial RElations Observatory, which will launch two satellites flung ahead and behind the earth (but because of the physics involved, they have no way of stopping them, because they won't have enough fuel to stop.

    (and there's also the Japanese Solar-B project, which is the successor to Yohkoh, set for launch next year)

    But in my opinion, the most significant solar observing satellite in planning is SDO, the Solar Dynamics Observatory. (and I say this purely from an IT standpoint) SDO will be at an inclined geosyncronous orbit -- so it will be able to talk to a single antenna the whole time -- rather than storing up its data, and then sending it down to earth once a day, it will be sending a constant stream of full resolution data.

    And we're not talking about the 1megapixel images from SOHO/EIT or SOHO/TRACE instruments -- or even the 4megapixel from STEREO/SECCHI. We're talking about 16 megapixel images, every 10 seconds from one of the instruments, with a planned terrabyte of uncompressed data per day.

    Oh -- and I work for NASA contractor, and am assigned to work on STEREO and VSO (the Virtual Solar Observatory, a search engine for solar physics data).

    I'm guessing that someone has probably come up with a VESA compliant mount for two screens, or if they haven't, you could probably make your own from an existing base, a bit of sheet steel, a drill, and a few screws ... and then you'd be able to just recycle existing monitors.

    Of course, the real issue the is stability of the base ... how high is the center of gravity, and what is the span of the base, so that we can compute the eccentricity required to tip it?. (it'd be more stable to just place two screens next to each other, and if you want them to stay in place, try a little bit of VHB or duct tape.)

    I would think that the advantages to the small footprint would be those that couldn't fit two monitors side by site normally -- which would mean it'd be extending over the edge of the desk, and has that much further to fall when someone bumps it. (unless you VHB it down to the desk, of course)

    I'd like to build on this, in all seriousness.

    If you remove all of the monotonous tasks, then you run the risk of every person needing a significant level of ability for the whole system (department, company, whatever) to operate smoothly.

    Unfortunately, those were the types of roles that you'd typically use for interns and other inexperienced employees. You could see what their learning ability was, and how out how well their work ethic and personality meshed with the organization.

    By over optimizing, you can reach the point where all employees must've gotten their initial experience from some other group. You have to trust their references, and your screening processes to find the employees that aren't complete crap.

    Yes, the external experience can help the organization, by providing new input, and potentially compare your processes to others that they've seen that were more efficient. But likewise, you run the risk of bringing in highly compensated employees that you're going to have to get rid of, or that can't really pull their weight and drag down the group.

    This year, I was given the opportunity to bring in an intern. The organization may want interns, but for me, because of the amount of time that I'd have to spend explaining what needs to be done to the internet, I'd most likely lose out overall in my productivity. It would be better for the company long term to bring in interns, but they left the decision in my hands, and I'm concerned with my short term deadlines.

    • It's taking twice as many clicks to get to the information they want, but they're more satisfied with the results. (this can't be gotten from just log analysis).

    • Profits are down.

    If you define goals based on metrics, then you can test to see if the person/group/company did or didn't reach their intended goal. Looking at the stats after the fact, and just trying to come up with something to support your opinion is going to result in a load of crap.

    • Users with browser X never make it to the 'checkout' page
    • Users with browser X always seem to stop on the (whatever) page.

  13. multiple revenue streams is not always good. on Gates on Google · · Score: 1

    Let's think about this -- we have a massive company who is deciding to branch out into new fields. They can't focus their best talent on the really important projects (like Longhorn, which they keep stripping features from), and so they have to spread themselves thin (MSN, MSNBC, XBox, Office, Windows, WebTV, monopoly problems, Google competition, etc.)

    They've lost sight of where their company's real core business is. In some ways, a forced seperation might have helped Microsoft to keep this from happening.

    Yes, there's a need to branch out into new fields so that you can bring in new revenue streams and diversify in case something bad happens, but you need smart growth -- sometimes, projects need to be killed. One of the worst things for a company can be a higher up exec's pet project, because they'll keep directing funding to it even when it's overly risky.

    • the likelihood of that vulnerability being realized
    • the impact if that vulnerability were realized
    • any mitigation that has been done to reduce the chance of it being fully realized and exploited.

    Risk = Threat * Vulnerability * Impact / Countermeasures

The impact, if this happened on a weekend could result in the lost of the entire building. Countermeasures include fire extinguishers, sprinklers, temperature alarms, off site backups, redundant servers, etc. You can never get rid of the vulnerability, because there is always a chance of that fire happening.

    Example 2: There is a possibiliy of all of the system administrators quitting, leaving you with no operations staff. This can be mitigated by treating them with respect, not forcing them to wear ties to work, and paying them better.
