    With a low noise floor, today could be a good day for HF DX enthusiasts. Even the 6m band is producing some contacts, both within North America and across the pond into Europe. 10m enthusiasts might also find TEP conditions into South America. 15m and 20m are open for ...

  3. Space Weather and HF Radio Propagation - 5/1/2013

    by , May 1st, 2013 at 10:20 PM (Virtual Thoughts for a Virtual World)
    The sunspot count is up to 165, with AR1730 and AR1731 still holding potential for significant flaring. The KP index is slightly up as well, peaking at 4 in the past 24 hours and now settling back down to 3. The Kp index could rise again when the previously mentioned increased solar wind from a coronal hole likely arrives at Earth towards weekend.

    The sunspot number is up to 136, with sunspots AR1730 and AR1731 holding potential for significant flaring. Increased solar wind from a coronal hole should arrive at Earth later this week. As for now, the Kp index is relatively quiet.

    10m band enthusiasts, especially long the east coast, might find a TEP opening into South America today. Otherwise, the 15m and 20m bands should be open for business into Europe.
  5. Space Weather and HF Radio Propagation - 4/26/2013

    by , April 26th, 2013 at 12:26 PM (Virtual Thoughts for a Virtual World)
    The Kp index is currently at 5 as increased solar energy is buffeting Earth's magnetosphere, sparking minor geomagnetic storming. The energy is arriving via the coronal hole mentioned earlier this week.

    The sunspot number is 93, and sunspot AR1726 is still holding potential for powerful flares, though it is starting to move away from the Earth-side of the sun.

    Given the Kp index and geomagnetic flux, 20m ...
  6. Space Weather Update: Sunspot AR1726

    by , April 22nd, 2013 at 03:54 PM (Virtual Thoughts for a Virtual World)
    Sunspot AR1726 is now showing a delta class magnetic field, meaning an increasing chance of a significant flare event. The percentages are weighted more towards a M-class flare at 40% odds, though there is an estimated 15% chance of a more powerful X-class flare. Either way, given the location of AR1726, any produced flares are likely to track towards Earth. Sunspot AR1726 is the oval-shaped formation appearing in the upper-right quadrant of the following images.

    The sunspot number is down to 76, with sunspot AR1726 showing significant size and potential for flaring. Increased solar wind from a coronal hole should arrive at Earth later this week, towards weekend. Meanwhile, the Kp index is currently quiet.

    The upper HF bands are not looking impressive this morning, though there appears to be a limited TEP opening on 10m 0between portions of North and South America. 20m is a better ...
  8. Learning Powershell

    by , April 18th, 2013 at 06:42 PM
    If you haven’t noticed lately PowerShell in Windows is becoming the norm and with future OS/application releases of Window (unless you have been living under a rock). For some windows administrators this is going to be a very tough move since they grew up on the GUI and haven’t really done much when it comes to command line anything (unless they were forced to do it for a fix of some sort). Over the last few days, I've been working with some co-workers who are doing some pretty cool things when ...

    The sunspot number is down to 89, and while sunpot AR1723 was holding potential for strong flaring, it now appears to be losing energy. A coronal hole is streaming increased solar wind, which should arrive at Earth this weekend. Otherwise, the Kp index is current.y quiet.

  10. Red-Braised Pork

    by , April 14th, 2013 at 04:06 PM (A Fish Dinner in Memison)
    We just got Fuschia Dunlop's latest cookbook, Every Grain of Rice. Her other books have been really good, and we happened to have some high-quality pork belly -- uncured bacon with the rind still on. So we decided to make this tonight:
    Red-Braised Pork

    1¼ lb (500g) boneless pork belly, with skin, or shoulder
    2 tbsp cooking oil
    4 slices of unpeeled ginger
    1 spring onion, white part only, crushed slightly
    2 tbsp Shaoxing wine
    2 cups plus 2 tbsp (500ml) chicken
    ...
