太陽閃焰X8.11及影響台灣地區電離層狀況

這次發生在2026年02月2日清晨的7點46分(0201 00h58m UT) 太陽色球層X8.11級的閃焰爆發. 當時發生時間持續23h50m-01h10m左右.
台灣地區在7點58分爆發最高x8.1級,並未在中午,D層電離達到吸收最大期間. 因影響僅在10MHz的臨界吸收頻率. 但HF的電波傳導所需的F層電離,其自由電子密度已經因太陽日照逐漸增加再加上太陽這次的X8.1級的X光通量進入. 所以10MHz傳導瞬間達到增益電波效果.

 這台定價高達 US$99,000（折合約 HK$772,200）的黑科技裝置，不僅標榜全自動觀星，更首度引入了 Canon 的影像技術。 Hyperia 系統核心是一枚 4,500 萬像素的全片幅感光元件，從參數推斷極有可能是來自 Canon EOS R5 Mark II，並配上一組由 17 枚鏡片構成的 150mm 口徑的折射式鏡頭，光圈為恆定 F4。

太陽閃焰的電磁輻射單位是以輻照度(irradiance)入射於曲面時每單位面積的功率。NOAA是以閃焰爆發出的輻射發射率(radiant emittance，radiant exitance)是從每單位面積曲面輻射出的功率。其物理量的單位為瓦特/每平方公尺（W/m2 CGS單位).

NOAA 定義太陽閃焰爆發能量和等級分類:
Solar flare intensities cover a large range and are classified in terms of peak emission in the 0.1 – 0.8 nm spectral band (soft x-rays) of the NOAA/GOES XRS.
The X-ray flux levels :
A level (nominally starting at (10-8 W/m2)
B level (≥ 10-7 W/m2)
C flares (10-6 W/m2)
M flares (10-5 W/m2)
X flares (10-4 W/m2) <------The level observed this time

MoM-z14是已知最遙遠的星系。它於2025年5月16日被發現，紅移值為z = 14.44。圖中所示為該星系在大爆炸後約2.8億年形成時的景象。根據宇宙演化時間線，MoM-z14形成於早期宇宙的再電離時期，當時中性氫開始因最早天體輻射的能量而電離。

 Seestar Companion 1.0.2 is now available
After a short pause, I’m back with a new release of Seestar Companion — a desktop app designed for ZWO Seestar S30, S30 Pro and S50 users.
Seestar Companion does not process images and does not replace PixInsight, Siril or DSS.
Its purpose is different: it helps you understand how good your Seestar session really was, why, and how it compares to other nights.
What it does
• Reads Seestar session folders directly (no special exports)
• Gives each session a quality score with a clear, human explanation
• Takes into account integration time, target altitude, Moon impact and consistency
• Lets you compare multiple nights on the same target
• Exports clean PNG / social-ready summaries
New in version 1.0.2
• Frame Quality Analysis (Good / Borderline / Not good)
• Non-destructive workflow (original frames are never deleted)
• Optional safe copy of analyzed frames into dedicated folders
• UI refinements and clarity improvements
The software is offline-first, multilingual, and actively developed based on community feedback.
A macOS version is planned.
 I’ve just published the first official video overview explaining how it works and what’s new.
More details are available on the Astro Imaging Toolbox website:
 astroimagingtoolbox dot com / seestar-companion
As always, feedback from Seestar users is very welcome.
