• Sailing is all about the Weather.

    Big into the exploration of Atlantic Hurricanes since Katrina came uninvited into his world, James (Jim) Gurley (JamesG161) has followed every Tropical Storm birthed in Atlantic, Gulf and Caribbean waters since. Being a boater, he knows that we often need more time to prepare than we get from the TV weather folk. Jim relies on the science of storm development to share early warning info with friends and fellow boaters.

    Early in 2018, Jim and John Shepard, (JSSailem) started to chat about the weather data available. John asked Jim to help forecast Pacific NW storms, and this morphed into discussions on weather forecasting.

    For John, sailing in the PNW is sometimes hit and miss. One day is ugly, then a string of beautiful days but no wind, followed by a series of blue-sky days and 12 knot breezes. Being ready for those great sailing days means you need to look to the Pacific Ocean and what is brewing. John has been into Pacific NW Weather since the 1970’s when his first PNW November storm hit bringing more than 40 days and 40 nights of continual rain.

    Together we want to share information, new APPs, safety, and thoughts about letting the weather help you. Identify some of the resources for sailors and help prepare you for your next sailboat outing.

    It is far better to go out on the water knowing what to expect in weather terms, than to be out on the water and see dark ominous clouds suddenly appear, unprepared.

Solar activity brings spots breakout

This activity is a start for our sun to break out from the solar minimum.

New milestones for SC25

January continued the high levels of solar activity. So far this month, already a few dozen of M-class flares have been recorded as well as 3 X-class flares, the most recent one an X1.0 event that took place on 10 January (see the STCE Newsitem at Triple X | STCE ). The solar disk was peppered with big and small sunspots, as can be seen in the white-light image underneath taken on 15 January by the solar telescopes of the Royal Observatory in Belgium (USET - SIDC - Solar Influences Data Center). The image has been colourized and contrast enhanced. Using eclipse glasses, the big spot in the lower left has become visible to the naked eye. This will remain so for the next few days as the sunspot remains close to the Sun's central meridian ("north-south" line).

We were lucky the Flares were not pointed at the Earth.:clap:

Why lucky?

They cause satellite disruption , like GPS and Communications.

X-ray Flux also hits the Astronauts on the Space Station, but early warnings lets them get into protective barriers.

@jssailem and me are preparing a post on Sun's effects on the Oceans and Sailing.
