Solor activity has some affect on the electrical grid and on satellites. However, the folks operating the layer 0 and layer 1 facilities usually do their jobs well enough it rarely has any noticable affect on the upper layers. The most noticible affect for most network operators is they get some extra static or sparkles on their CNN monitor in the NOC.

Solarmax effects

The primary expected effect of "solarmax" flare activity is that Sean Donelan will have to buy a new keyboard, because he'll wear out his old one. If you have any spares you'd like to contribute, send them to me and I'll make sure Sean (or someone who's name sounds the same) gets them.

Been keeping an eye on CAISO since last summer. They seem to be on some type of access timer. Never can get in there during the wee morning. Not sure at what time they open the gates. As for the SystemStatus loggings. These are good for identifying which alert level, but you need to go to the "Newsroom" link to see the latest updates, i.e., announcements about rolling blackouts etc. K > -----Original Message----- > From: Roy [mailto:garlic@garlic.com] > Sent: Thursday, January 18, 2001 7:53 AM > To: nanog(a)merit.edu > Subject: Re: California -- STAGE 3 POWER EMERGENCY...

SOLARMAX and Power Interruptions
by Karyn Ulriksen 18 Jan '01

18 Jan '01

I recently saw the documentary Solarmax at Portland's OmniMax theatre, which was very interesting (not too mention a great ride in omnimax theatre!). The documentary on the sun outlined the impact of solar flares, especially the ones that occur every 11 years when the sun reverse rotation. The last one, 11 years ago, affected power grids and satellite systems (then in toddler stage). Does anyone have any information on the expected impact of this year's solarmax on power grids and satellite communication? Or was the documentary more hype than fact? --------------------------------------------------------------------- Best regards, Karyn Ulriksen Director of Network Operations PublicHost, A SiteStream Company 1 Jenner, Suite 100 Irvine, California 92618 USA Phone: (949) 743-2000 email: kulriksen(a)publichost.com URL: http://www.publichost.com ===========================================

California -- STAGE 3 POWER EMERGENCY... AGAIN
by Matt Clauson 18 Jan '01

18 Jan '01

from the California Independent System Operator website, at: http://www.caiso.com/awe/systemstatus.html Current Active Notice(s) STAGE 3 EMERGENCY NOTICE [200100652] Effective 01/16/2001 at 07:20 the California Independent System Operator has implemented Stage 3 of the Electrical Emergency Plan. The Plan has been implemented for the following reason(s): Insufficient reserves and energy. Stage 3 is expected to be in effect from HE 8 through HE 24. Participating transmission owners are to notify the Utility Distribution Companies within their operational areas. Stage 3: Operating reserves are expected to fall below 1-1/2%. The UDC will implement their electrical emergency plan and/or other load dropping to effect 0 MW of involuntary firm demand reductions (i.e., in addition to ALL Interruptible Service reductions) no later than hours. This message is from Market Operations at the California ISO. Notice issued at: 01/16/2001 07:20 [fin] Have you checked your generator today? --mec ----- End forwarded message -----

I suspect the availability of data is not the only/key issue here. If pressed (asked correctly, etc.), most vendors can provide some approximation of worst case system or per-subsystem current requirements, whether they have done/can spell NEBS or not. Even though it is non-trivial to measure instantaneous peak drain empirically, there are other ways to get reasonable bounds on it, and doing so is a routine practice of hardware engineers. A reason that the most careful power capacity forecasts (in particular) may *seem* to be perpetually optimistic, might be the needlessly high peak to average drain ratio of (most?) equipment. If customers can convince vendors that they have more concern about the ancillary costs of operating equipment, vendors might be induced (pun!) to make some nominal sacrifices in cost and MTBF to include features like inrush current limiting, and sequencing. Get your RFPs ready. Regards, Andrew Bender taqua.com

> > Blocks 7 and 8 went out around 11 PM local (that's almost an hour ago now) > What I meant to say here (as several have pointed out) is that blocks 7 and 8 went out at 11 *AM* I've been converting between Pacific time and Eastern time all day, and keep getting the sign bit mixed up. Meanwhile, more accurate (but not guaranteed to be correct) data: Block 5 (the part that wasn't hit yesterday), Block 6, and Block 7 were scheduled out at 10 AM and scheduled back by 11:40 AM Block 8 and Block 9 were scheduled out at 11 AM and scheduled back by 12:40 PM Further outages were suspended at noon, until 5 PM, when it is expected that, barring a miracle, the last of Block 9 and all of Block 10 will be shut down. -matthew kaufman Tycho Networks/DSL.net matthew(a)tycho.net
